Silver Peso of Philip V. A major drive of the Spanish colonization of the Americas during the late 15th and 16th centuries was the discovery, production, and trading of precious metals at a time when there was a severe shortage of them.
Between 1500 and 1800, Bolivia, Peru, and Mexico made of 85% of the world's total silver production. [17] Silver mining required large amounts of mercury to extract the metal from ore. In the Andes, the source was the Huancavelica mercury mine; Mexico was dependent on mercury from the Almadén mercury mine in Spain.
Annual US mined silver production. Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the "Crime of 73", but silver mining continues today.
Silver is usually found in nature combined with other metals, or in minerals that contain silver compounds, generally in the form of sulfides such as galena (lead sulfide) or cerussite (lead carbonate). So the primary production of silver requires the smelting and then cupellation of argentiferous lead ores, a historically important process. [87]
In addition, cupellation, developed in the 8th century, was more often used for the refinement of lead-silver ores, to separate the silver from the lead (Bayley 2008). Parallel production with more than one technical method, and different treatment of ores would occur wherever multiple ores were present at one site. (Rehren et al. 1999).
Cumulative silver production through 1981 totaled 490 million troy ounces (15 million kg). [1] However, only about 10% of Arizona's silver production came from silver mining. More than 80% of the state's silver was a byproduct of copper mining; other silver came as a byproduct of lead, zinc, and gold mining. [1]
Over the past year, I have tracked for my readers a series of headaches suffered by legendary silver producer Hecla Mining (NYS: HL) , culminating in Hecla's Hangover: the temporary closure of the ...
Silver mining in Nevada, a state of the United States, began in 1858 with the discovery of the Comstock Lode, the first major silver-mining district in the United States. Nevada calls itself the "Silver State." Nevada is the nation's second-largest producer of silver, after Alaska. In 2014 Nevada produced 10.93 million troy ounces of silver, of ...
