Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of …
Refining 101 | Gold & Precious Metal Refining | Garfield Refining
Refining is the process of purifying an impure metal. It's easiest to think of precious metals refining as a method of recycling. The refining process takes products or byproducts containing precious metals (such as jewelry or dental scrap ) and isolates the metals back into more purified states for recirculation.
Gold processing
Gold processing - Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present …
