In such processes, silver follows the nonferrous metal in question through its concentration and smelting, and is later purified out. For example, in copper production, ...
WhatsApp: +86 18838072829At current gold prices this is worth about US600. Both smelter treatment charges and oxidation or bioleach costs are at least 200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around Clearly this is a function of gold price, but in the current gold price and cost ...

Generally, silver is also dissolved by the cyanide solution and follows the gold through the process ...
WhatsApp: +86 18838072829Utah Ore Sampling Company was an independent third party that assayed the mineral content, and amount of ores shipped from mines to smelters. They got their start in Park City, at a joint trackage location between UP and DRGW inside UP's wye. That location closed in 1917 when the Murray plant was built, and the existing structure was built in ...
WhatsApp: +86 18838072829Another phase of the question is illustrated by the case of a mine which is shipping about one hundred tons of gold silverleadzinc ore per day to a custom mill. While the milling charges are reasonable, the custom plant cannot rearrange its flowsheet for this particular ore, and does not recover the zinc.
