The molten metal is called as collector metal. Commonly used collector metals include iron, copper, nickel, leadcopper and nickel matte. And then, the extracted valuable metals must be further treated in order to separate and purity them. Many metals like lead, copper etc., can be extracted through pyro metallurgical process.

The hydrometallurgical copper extraction processes of the present teachings generally including two steps: a conditioning or activating step using low concentrations of ammonia and ammonium in an aqueous solution; and an acid leaching step. The processes of the present teachings can be performed at low temperature, for example, at ambient temperature, and at atmospheric pressure.
May 12, 2019· Leaching, the recovery of copper from the drainage water of mines, is a well established method of the extraction of minerals as early as the eighteenth century, but until about 25 years ago miners did not realize that bacteria take an active part in the process.

Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized.
The copperbearing aqueous phase is advanced to the electrowinning (EW) stage of the process while the barren organic phase is returned to the extraction stage of the process. In the electrowinning stage of the process the copper is reduced electrochemically from copper sulfate in solution to a metallic copper cathode.
OVERVIEW OF COPPER EXTRACTION The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks. The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor. When the crushed ore falls onto the
