Abstract The roots of the patio process, that relied on the action of mercury to extract silver from ores that did not contain lead, lie in alchemy and European metallurgy, two areas that overlapped with pragmatic ease in the sixteenth century. Since mercury was known to extract gold, the same recipe applied to gold was used initially to extract silver from its ores. …

Silver minerals are known to have slow leaching rates and low overall extraction and require a high concentration of cyanide and a long retention time to maximize leach extraction. Their response to cyanidation is considered mild to moderately refractory, largely due to complex mineralogical compositions. New research on improving the dissolution of silver …

Lake Valley was a silver-manganese mining district during the late 19th century. Silver was discovered in 1876, and the area was extensively mined until the silver crash in 1893 (Donegan et al., 1965; McLemore and Nutt, 2002). The Lake Valley district includes the famed Bridal Chamber, which was found in 1881.
