Get PriceApr 24, 2017· The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace.
Get PriceThe method utilized is called the Parkes process, where the silver is removed from lead and some other types of metal through a liquidtoliquid extraction procedure. Silver can also be extracted from copper and zinc through a similar process in which the silver is purified by a nitrate solution. Another source of silver is refined from gold mines.
Get PriceThe patio process is a process for extracting silver from process was invented by Bartolomé de Medina in Pachuca, Mexico, in 1554.
