Gold Smelting Refining Process
The Inquartation and Parting Process is based on the solubility between gold, silver and copper. Initially there is an impure product obtained by smelting that must be grained to improve the surface area so that the metallic product can be attacked with nitric acid in order to dissolve copper and silver and the leaching residue is metallic gold.

PHASES OF A MINING PROJECT ELAW
Proposed mining projects vary according to the type of metals or materials to be extracted from the earth. The majority of proposed mining projects involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of largescale mining projects involving

Processing, smelting and refining gold | World Gold Council
***copper remains in gold The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

Copper extraction Wikipedia
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
