Get Price· The common extraction process is to enrich silver into lead, zinc, and copper concentrates, and then extract silver by smelting. However, in the smelting process, the silver in the lead concentrate enters the crude lead with the main metal, the silver in the copper concentrate enters the matte.
Get PriceThe journey from ROM ore to concentrate and finally metal travels through many operations of liberation, separation, concentration, and extraction before it reaches the end users. These activities have been diagrammatically summarized in Figs. and A panoramic view of State of the Art zinc and lead smelting is depicted in Fig.

Get PriceThe process begins by adding the sulfideassociated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is .
Get PriceTo isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with steel balls.
Get Price· Roasting is the process of heating a sulfide ore to a very high temperature in the presence of air. This process is generally applied to sulfide minerals. The sulfide is converted to an oxide during roasting, and sulfur is released as sulfur dioxide, a gas. The sulfur dioxide obtained is used in the manufacture of sulphuric acid.
