Silver mining is the extraction of silver by mining . Silver is a precious metal and holds high economic value. Because silver is often found in intimate combination with other metals, its extraction requires the use of complex technologies. In 2008, approximately 25,900 metric tons of silver were consumed worldwide, most of which came from mining. Silver mining has a variety of effects on the environment, humans, and animals.

From 1872 to 1920, a surge of technological innovation increased global silver production to 120 million ounces produced per year. New silver deposits had been discovered in Australia, Canada, United States, Africa, Mexico, Chile, and Japan, and by

After separating it from the ore, amalgam is roasted and mercury vapor escapes into the atmosphere and also makes its way into rivers and soils. From the years 1545 to 1803, over 25,000 tons of silver were produced using amalgamation in

In the first half of the 19th century Chilean mining revived due to a silver rush in the Norte Chico region, leading to an increased presence of Chileans in the Atacama desert and a shift away from an agriculture based economy. The country of Argentina was named after its silver resources by Spanish conquistadors; Argentina

The amalgamation methods have proven problematic. It is estimated that 90% of the mercury consumed in the United States from 1850 to 1900 was used to extract silver and gold . An estimated 257,400 tonnes of mercury were lost to the environment in this process in

4290-611: The decade following the First World War, the Colorado National Guard was plagued with low enlistment numbers and limited funding. Despite this, it was mustered against striking Denver Tramway Company workers in August 1920, where the Guard’s limited numbers meant it was unable to effectively break up the strikers. In June 1921, the Arkansas River flooded, killing at least 120—with some estimates of up to 1,500 dying—and destroying hundreds of homes in and around Pueblo. The National Guard and local American Legion chapters helped rescue and recover victims. The Colorado Army National Guard added
4368-412: The end of 1920, global production surged to 190 million ounces annually. The mining techniques during the 1900's had also dramatically changed. Seam-assisted drilling, mine dewatering , and improved haulage all contributed to the spike in silver production in the 1900's. By 2019, technological innovation has allowed silver production to grow to almost 800 million ounces per year. Mercury amalgamation

By 1,200 BC, silver mining shifted into the mines of Laurion in Greece, and continued growing the surrounding empire. The silver mines at Laurion were very rich and helped provide a currency for the economy of ancient Athens , where the process involved mining the ore in underground galleries, washing and then smelting it to produce

Silver mining operations in indigenous communities lead to increased hunting pressure and a decline in traditional practices due to population growth and better hunting technologies. This affects local animal populations and cultural rituals. Employment in mines results in longer working hours, reducing time for traditional activities like hunting and fishing , which threatens

By the year 100 AD, the epicenter of silver mining transitioned into Spain, where the Roman Empire flourished. The Romans took over silver mining in Spain from Carthage after their acquisition of Carthaginian territories there following the Second Punic War . Extraction of silver from lead ore

As a byproduct of the mining of lead and copper, silver ores are often purified by froth flotation . After froth flotation, silver is extracted by a cyanide process , akin to technology used for gold extraction . In some cases, the ore is treated by smelting before cyanide treatment. Silver

Upon reaching the camp and witnessing the aftermath of the Holocaust crimes perpetrated there, enraged members of the unit killed upwards of 35 SS camp guards and workers as reprisal. Other elements of
5382-1154: The spreading of ecological knowledge and cultural practices. While mining can provide economic resources for purchasing hunting equipment, it also accelerates the decline in traditional lifestyles and cultural heritage, impacting food security and community cohesion in indigenous populations. Mining projects also pose significant threats to family integrity, manifesting in decreased quality and quantity of family time due to long working hours and associated stressors, as well as disruptions to traditional familial roles and responsibilities. Limited time for communication and support may exacerbate existing problems within families. This leads to fragmentation and potential conflicts, with spouses having increased household responsibilities and children facing adverse consequences such as behavioral issues and academic struggles. Silver mining in indigenous communities lead to cultural shifts, with Western values often replacing traditional ones. While some argue that mining can promote cultural values such as independence and pride through job creation and increased disposable income, others highlight negative impacts such as

During the following week, strikers sought revenge against the mining companies and National Guard, launching dozens of deadly attacks across the state in what became known as the 10-Day War.
