Silver mining - Wikipedia

Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. As such, most silver produced is refined from sulfide ores such as galena (lead) or chalcopyrite (copper) which contain small amounts of silver. Many of these ores are mined for their value as sulfide ores, and silver is extracted as a valuable by-product, however, some ores are mined explicitly for their silver value. Flotation separation is a key step in this complicated process. Silver mineralizes most commonly as arge

How silver is made - material, making, history, used ...

A method called the cyanide, or heap leach, process has gained acceptance within the mining industry because it is a low-cost way of processing lower-grade silver ores. However, the ores used in this method must have certain characteristics: the silver particles must be small; the silver must react with cyanide solutions; the silver ores must be relatively free of other mineral contaminants ...

Mint and private assayers would then refine the doré bars to an acceptable purity, 999 fine, gold bullion, with the silver and base metals removed. By the time of the California gold rush , mints were moving away from the age-old process of cupellation to "part" bullion and moving toward the acid refining process developed by chemist Joseph Louis Gay-Lussac for the French mint.

The Mining Process - Newmont Corporation - About Us

This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution. We then “strip” the gold from the carbon by washing it with a caustic cyanide solution. The carbon is later recycled. Next, we pump the gold-bearing solution through electro-winning ...
