148-567: Alfred Chester Beatty (7 February 1875 – 19 January 1968) was an American-British mining magnate and philanthropist. A successful businessman, Beatty was given the epithet "the King of Copper " in reference to his fortune. He became a naturalised British subject in 1933, was knighted in 1954, and was made an honorary citizen of Ireland in 1957. He collected African, Asian, European and Middle Eastern manuscripts, rare printed books, prints and objets d'art. After moving to Dublin in 1950, he established

At the macroscopic scale, introduction of extended defects to the crystal lattice , such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is usually supplied in a fine-grained polycrystalline form, which has greater strength than monocrystalline forms. The softness of copper partly explains its high electrical conductivity ( 59.6 × 10 S /m ) and high thermal conductivity, second highest (second only to silver) among pure metals at room temperature. This

This is due to the low plasma frequency of the metal, which lies in the red part of the visible spectrum, causing it to absorb the higher-frequency green and blue colors. As with other metals, if copper is put in contact with another metal in the presence of an electrolyte , galvanic corrosion will occur. Copper does not react with water, but it does slowly react with atmospheric oxygen to form

His son had bought a home in County Kildare in 1948, which probably prompted Beatty to look favourably on Ireland as a home, especially given his Irish roots: both his paternal grandparents were born in Ireland. Beatty was also seriously considering long-term plans for his collection. Concerned that it would be dispersed if he were to leave it to a large institution, he found another solution. His purpose-built library on Shrewsbury Road in

The United Kingdom responded with an ultimatum for Germany to cease military operations, and on 3 September, after the ultimatum was ignored, Britain and France declared war on Germany. During the Phoney War period, the alliance provided no direct military support to Poland, outside of
2368-765: A pretext to worsen relations. On 29 August, Hitler demanded that a Polish plenipotentiary immediately travel to Berlin to negotiate the handover of Danzig , and to allow a plebiscite in the Polish Corridor in which the German minority would vote on secession. The Poles refused to comply with the German demands, and on the night of 30–31 August in a confrontational meeting with the British ambassador Nevile Henderson , Ribbentrop declared that Germany considered its claims rejected. On 1 September 1939, Germany invaded Poland after having staged several false flag border incidents as

Having committed himself to the Allied war effort during the Second World War and served on a number of Churchill's committees, he was shocked by the Labour party victory. He told a meeting of stockholders that London was no longer the centre of the mining world and that "the position would deteriorate while high taxation, unjust duties and rigid controls stopped new mining projects being launched". There were other, personal, considerations, however, and his old spirit of adventure surely played

4736-762: Is one of the few metals that can occur in nature in a directly usable metallic form ( native metals ). This led to very early human use in several regions, from c. 8000 BC . Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC ; the first metal to be cast into a shape in a mold, c. 4000 BC ; and the first metal to be purposely alloyed with another metal, tin , to create bronze , c. 3500 BC . Commonly encountered compounds are copper(II) salts, which often impart blue or green colors to such minerals as azurite , malachite , and turquoise , and have been used widely and historically as pigments. Copper used in buildings, usually for roofing, oxidizes to form

10952-575: The Soviet Union and Mongolia . The Japanese doctrine of Hokushin-ron , which emphasised Japan's expansion northward, was favoured by the Imperial Army during this time. This policy would prove difficult to maintain in light of the Japanese defeat at Khalkin Gol in 1939, the ongoing Second Sino-Japanese War and ally Nazi Germany pursuing neutrality with the Soviets. Japan and the Soviet Union eventually signed
11100-738: The Soviet Union should be eliminated and aimed for the conquest of Ukraine , the Baltic states and Byelorussia . However, other senior German officials like Ribbentrop saw an opportunity to create a Euro-Asian bloc against the British Empire by inviting the Soviet Union into the Tripartite Pact. In November 1940, negotiations took place to determine if the Soviet Union would join the pact. The Soviets showed some interest but asked for concessions from Finland, Bulgaria, Turkey, and Japan that Germany considered unacceptable. On 18 December 1940, Hitler issued
11248-587: The Soviet Union was ever signed, although the state of war between the two countries was terminated by the Soviet–Japanese Joint Declaration of 1956 , which also restored full diplomatic relations between them. World War I had radically altered the political European map with the defeat of the Central Powers —including Austria-Hungary , Germany , Bulgaria , and the Ottoman Empire —and
11396-568: The United Kingdom and France guaranteed their support for Polish independence ; when Italy conquered Albania in April 1939, the same guarantee was extended to the Kingdoms of Romania and Greece . Shortly after the Franco - British pledge to Poland, Germany and Italy formalised their own alliance with the Pact of Steel . Hitler accused the United Kingdom and Poland of trying to "encircle" Germany and renounced
11544-538: The United Kingdom attacked on 3 July in an attempt to prevent its seizure by Germany. The air Battle of Britain began in early July with Luftwaffe attacks on shipping and harbours . The German campaign for air superiority started in August but its failure to defeat RAF Fighter Command forced the indefinite postponement of the proposed German invasion of Britain . The German strategic bombing offensive intensified with night attacks on London and other cities in
11692-455: The United Kingdom. The Germans turned south against the weakened French army, and Paris fell to them on 14 June. Eight days later France signed an armistice with Germany ; it was divided into German and Italian occupation zones , and an unoccupied rump state under the Vichy Regime , which, though officially neutral, was generally aligned with Germany. France kept its fleet, which
11840-689: The United States was assisting China and the Western Allies, and had amended the Neutrality Act to allow "cash and carry" purchases by the Allies. In 1940, following the German capture of Paris, the size of the United States Navy was significantly increased . In September the United States further agreed to a trade of American destroyers for British bases . Still, a large majority of the American public continued to oppose any direct military intervention in

Faced with an imminent invasion of the Japanese archipelago ,
12136-517: The Western Allies invaded German-occupied France at Normandy , while the Soviet Union regained its territorial losses and pushed Germany and its allies westward. At the same time, Japan suffered reversals in mainland Asia, while the Allies crippled the Japanese Navy and captured key islands . The war in Europe concluded with the liberation of German-occupied territories ; the invasion of Germany by
12284-590: The Yellow River ; this manoeuvre bought time for the Chinese to prepare their defences at Wuhan , but the city was taken by October. Japanese military victories did not bring about the collapse of Chinese resistance that Japan had hoped to achieve; instead, the Chinese government relocated inland to Chongqing and continued the war. In the mid-to-late 1930s, Japanese forces in Manchukuo had sporadic border clashes with
12432-611: The aerial Battle of Britain and the Blitz , and naval Battle of the Atlantic . Through a series of campaigns and treaties, Germany took control of much of continental Europe and formed the Axis alliance with Italy , Japan , and other countries. In June 1941, Germany led the European Axis in an invasion of the Soviet Union , opening the Eastern Front and initially making large territorial gains. Japan aimed to dominate East Asia and
12580-521: The affected areas is highly acidic, with a pH range of 2.1–4.9, and shows elevated electrical conductivity levels between 280 and 1561 mS/cm. These changes in water chemistry make the environment inhospitable for fish, essentially rendering the water uninhabitable for aquatic life. Numerous copper alloys have been formulated, many with important uses. Brass is an alloy of copper and zinc . Bronze usually refers to copper- tin alloys, but can refer to any alloy of copper such as aluminium bronze . Copper

Most copper is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Sites include Chuquicamata , in Chile, Bingham Canyon Mine , in Utah, United States, and El Chino Mine , in New Mexico, United States. According to
13024-686: The beginning of the Neolithic c. 7500 BC . Copper smelting was independently invented in different places. The earliest evidence of lost-wax casting copper comes from an amulet found in Mehrgarh , Pakistan, and is dated to 4000 BC. Investment casting was invented in 4500–4000 BC in Southeast Asia Smelting was probably discovered in China before 2800 BC, in Central America around 600 AD, and in West Africa about
13172-616: The beginning of the Pacific War include the start of the Second Sino-Japanese War on 7 July 1937, or the earlier Japanese invasion of Manchuria , on 19 September 1931. Others follow the British historian A. J. P. Taylor , who stated that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and the two wars became World War II in 1941. Other proposed starting dates for World War II include

He received a belated knighthood by Queen Elizabeth II in the 1954 Birthday Honours List for his contribution to the wartime effort. By
13616-527: The company, especially when sourced from fossil fuels, and from engines required for copper extraction and refinement. Companies that mine land often mismanage waste, rendering the area sterile for life. Additionally, nearby rivers and forests are also negatively impacted. The Philippines is an example of a region where land is overexploited by mining companies. Copper mining waste in Valea Şesei, Romania, has significantly altered nearby water properties. The water in
13764-403: The conflict well into 1941. In December 1940, Roosevelt accused Hitler of planning world conquest and ruled out any negotiations as useless, calling for the United States to become an " arsenal of democracy " and promoting Lend-Lease programmes of military and humanitarian aid to support the British war effort; Lend-Lease was later extended to the other Allies, including the Soviet Union after it
13912-571: The country's leading mining engineers. He bought a house on the East Side of New York and set up an office on Broadway as an independent mining consultant. Ninette and their daughter (little Ninette) joined him during the summer of 1907, and in October their son, Chester Jr, was born. In 1911, Grace died suddenly of typhoid fever . In 1912 he purchased Baroda House in Kensington Palace Gardens and moved with his two young children to London

Adolf Hitler , after an unsuccessful attempt to overthrow the German government in 1923, eventually became the Chancellor of Germany in 1933 when Paul von Hindenburg and the Reichstag appointed him. Following Hindenburg's death in 1934, Hitler proclaimed himself Führer of Germany and abolished democracy, espousing a radical, racially motivated revision of
14208-474: The curators), he changed his mind when the new director insisted on deciding for himself whether Beatty's collection met the museum's quality standards. The director also would not assure Beatty that his collection would remain intact, rather than being parcelled out to different departments. In 1950, at the age of 75, Chester Beatty handed over the reins of Selection Trust to his son Chester Jr and relocated to Dublin, taking many by surprise. The reason often cited
14356-522: The deprotonated amide ligands. Complexes of copper(III) are also found as intermediates in reactions of organocopper compounds, for example in the Kharasch–Sosnovsky reaction . A timeline of copper illustrates how this metal has advanced human civilization for the past 11,000 years. Copper occurs naturally as native metallic copper and was known to some of the oldest civilizations on record. The history of copper use dates to 9000 BC in
14504-454: The depths of the Pacific Ocean approximately 3000–6500 meters below sea level. These nodules contain other valuable metals such as cobalt and nickel . Copper has been in use for at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900. As with many natural resources, the total amount of copper on Earth is vast, with around 10 tons in
14652-550: The discovery of iron smelting . Production in the Old Copper Complex in Michigan and Wisconsin is dated between 6500 and 3000 BC. A copper spearpoint found in Wisconsin has been dated to 6500 BC.

Indigenous peoples of North America around
14800-402: The distinction between military and civilian resources. Tanks and aircraft played major roles , with the latter enabling the strategic bombing of population centres and delivery of the only two nuclear weapons ever used in war. World War II was the deadliest conflict in history, resulting in 70 to 85 million deaths , more than half being civilians. Millions died in genocides , including
14948-683: The end of May completed the German conquest of the Balkans. Partisan warfare subsequently broke out against the Axis occupation of Yugoslavia , which continued until the end of the war. In the Middle East in May, Commonwealth forces quashed an uprising in Iraq which had been supported by German aircraft from bases within Vichy-controlled Syria . Between June and July, British-led forces invaded and occupied
15096-563: The existing understanding of pre-Constantinian textual history. With the New Testament books – Gospels and Acts (BP I), Pauline Epistles (BP II) and Revelation (BP III) – all dated to the third century, these documents were not only surprising for having survived the Diocletian persecutions at the beginning of the next century, but the dating moved New Testament scholarship back by at least one hundred years. The dating specifically of BP I (p45) to
15244-545: The fastest water exchange rate (speed of water ligands attaching and detaching) for any transition metal aquo complex . Adding aqueous sodium hydroxide causes the precipitation of light blue solid copper(II) hydroxide . A simplified equation is: Aqueous ammonia results in the same precipitate. Upon adding excess ammonia, the precipitate dissolves, forming tetraamminecopper(II) : Many other oxyanions form complexes; these include copper(II) acetate , copper(II) nitrate , and copper(II) carbonate . Copper(II) sulfate forms
15392-566: The first step of what its government saw as the country's right to rule Asia , staged the Mukden incident as a pretext to invade Manchuria and establish the puppet state of Manchukuo . China appealed to the League of Nations to stop the Japanese invasion of Manchuria. Japan withdrew from the League of Nations after being condemned for its incursion into Manchuria. The two nations then fought several battles, in Shanghai , Rehe and Hebei , until

In 1914, Beatty founded the London-based mining company, Selection Trust . The First World War delayed the company's expansion, but during the 1920s the business expanded to acquire interests in countries including the USSR , the Gold Coast (present-day Ghana ) and
15688-843: The former Chinese imperial capital of Peking after instigating the Marco Polo Bridge incident , which culminated in the Japanese campaign to invade all of China. The Soviets quickly signed a non-aggression pact with China to lend materiel support, effectively ending China's prior cooperation with Germany . From September to November, the Japanese attacked Taiyuan , engaged the Kuomintang Army around Xinkou , and fought Communist forces in Pingxingguan . Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai , but after three months of fighting, Shanghai fell. The Japanese continued to push Chinese forces back, capturing
15836-496: The gallery linked the main house to the garden library. In 1940, Beatty packed up the paintings and shipped them to New York for safekeeping during the Second World War. In 1949, Beatty decided to donate part of his collection of French nineteenth-century paintings to the Irish nation as a token of appreciation to the Taoiseach of the day, John A. Costello , for his support in facilitating Beatty's move from London. These are now part of

The war resulted in the military occupation of Ethiopia and its annexation into the newly created colony of Italian East Africa ( Africa Orientale Italiana , or AOI); in addition it exposed the weakness of
16280-510: The late 1940s, however, he had become disillusioned with Britain. Political deviations from his free-market values, coupled with increased foreign exchange restrictions impacted both his personal and collecting interests in Britain. Though he had initially envisioned deepening his relationship with the British Museum by donating his collection in its entirety (he had personally funded many of the museum acquisitions, and received expert consultations from
16428-511: The later spelling first used around 1530. Copper, silver , and gold are in group 11 of the periodic table; these three metals have one s-orbital electron on top of a filled d- electron shell and are characterized by high ductility , and electrical and thermal conductivity. The filled d-shells in these elements contribute little to interatomic interactions, which are dominated by the s-electrons through metallic bonds . Unlike metals with incomplete d-shells, metallic bonds in copper are lacking
16576-419: The level of <1% Cu. Concentration of the ore is required, which begins with comminution followed by froth flotation . The remaining concentrate is the smelted, which can be described with two simplified equations: Cuprous oxide reacts with cuprous sulfide to convert to blister copper upon heating This roasting gives matte copper, roughly 50% Cu by weight, which is purified by electrolysis. Depending on
16724-460: The mid-third century moved the understanding of when Christians accepted the four gospels as canonical to earlier than had previously been presumed. In 1917, recovering from a bout of pneumonia and Spanish influenza, Beatty, Edith and his daughter Ninette, traveled by boat to Japan and China. During this trip he acquired painted albums and scrolls and he continued to purchase Chinese, Japanese and south-east Asian manuscripts, textiles and artefacts for
16872-472: The modern world. The price of copper is volatile . After a peak in 2022 the price unexpectedly fell. The global market for copper is one of the most commodified and financialized of the commodity markets , and has been so for decades. The great majority of copper ores are sulfides. Common ores are the sulfides chalcopyrite (CuFeS 2 ), bornite (Cu 5 FeS 4 ) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These ores occur at

Cuprous halides with fluorine , chlorine , bromine , and iodine are known, as are cupric halides with fluorine , chlorine , and bromine . Attempts to prepare copper(II) iodide yield only copper(I) iodide and iodine. Copper forms coordination complexes with ligands . In aqueous solution, copper(II) exists as [Cu(H 2 O) 6 ] . This complex exhibits
17168-428: The ore, sometimes other metals are obtained during the electrolysis including platinum and gold. Aside from sulfides, another family of ores are oxides. Approximately 15% of the world's copper supply derives from these oxides. The beneficiation process for oxides involves extraction with sulfuric acid solutions followed by electrolysis. In parallel with the above method for "concentrated" sulfide and oxide ores, copper
17316-524: The outbreak of World War II , and after the war in the south of France. During his first trip to Cairo in the winter of 1913/14, he became interested in papyrus and Islamic manuscripts.

Greatly alarmed and with Hitler making further demands on the Free City of Danzig ,
18204-521: The remainder of his life between Dublin and the south of France. He was made a Freeman of Dublin in 1954 and was the first person granted honorary citizenship of Ireland in 1957. He continued to collect in the 1950s and 1960s, acquiring important Ethiopian manuscripts and Japanese printed material during that period. Beatty died in Monte Carlo in Monaco in 1968; his Irish estate was valued at £7 million. He
18352-431: The rest of his life. Beatty's reputation as a collector grew, and so did his network of advisers and agents. As in his business life, Beatty relied on the advice of experienced specialists but made the final decision on any purchase himself. By this time Edith was also establishing herself as a serious collector in her own right. While she was buying Impressionist and Post-Impressionist paintings and French furniture, Beatty
18500-557: The rest of the 20th century and into the 21st century. The United Nations was established to foster international cooperation and prevent conflicts, with the victorious great powers—China, France, the Soviet Union, the UK, and the US—becoming the permanent members of its security council . The Soviet Union and the United States emerged as rival superpowers , setting the stage for the Cold War . In

Finland refused to sign
21756-657: Was repulsed with heavy Italian casualties; the campaign ended within months with minor territorial changes. To assist Italy and prevent Britain from gaining a foothold, Germany prepared to invade the Balkans, which would threaten Romanian oil fields and strike against British dominance of the Mediterranean. In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa . The offensives were successful; by early February 1941, Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The Italian Navy also suffered significant defeats, with
