Thiourea for Extraction of Gold & Silver from Silver OresJan 10, 2018 . Extractions of 12.41 % silver and 1.55 % gold were realized after 15 minutes of leaching time. The final extractions of gold and silver was 45 % Ag and 2 % Au after one hour of leaching. If the ore is lean in silver, however, the second stage leaching may be not be feasible. It should also be pointed out that.ball mill for gold 2 copper 2 silver ore,pages - ERSEL Ağır Makine San. ve Tic.

In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock.
Silver ores were crushed (typically either in "arrastras" or stamp mills) to a fine slime which was mixed with salt, water, magistral (essentially an impure form of copper sulfate), and mercury, and spread in a 1-to-2-foot-thick (0.30 to 0.61 m) layer in a patio, (a shallow-walled, open enclosure).

Thus, the part dumped still has an important quantity of gold and other elements like silver or copper. Therefore cyanide is applied to the tails to dissolve these elements and recover some of it by adsorption using activated carbon.

Mining activity began in the DeLamar project area in May of 1863 when placer gold deposits were discovered in Jordan Creek, just upstream from what later became the town site of DeLamar. The placer deposits were traced up stream, beyond the DeLamar project area, and during the summer of 1863 the first silver-gold.
