4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.

Abstract—Gold and silver are capable of forming stable natural compounds with different elements. For gold 36 minerals are known: 10 in the class "Native metals, intermetallic compounds" and 26 in the class "Sulfides (selenides, tellurides, arsenides, antimonides, bismuthides)." For silver, 194 minerals are registered in the MMA, presented …

The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper. This is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver). The anodes are electrolytically refined in cells sketched in Fig. 8. There is a resemblance to the cell ...

Jhunalyn Parantar. Sulphide ores of copper are insoluble in dilute sulphuric acid leaching solutions, but a very high extraction can be obtained if the copper ore is in the oxidized condition. The problem is to convert the sulphide into the oxide form. This can be done by giving the sulphide ore an oxidizing-sulphatizing roast.
