This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
ABSTRACTMixed sulfide–oxide lead and zinc ores are generally composed of both sulfides and oxides. The dissolution of sulfides is more difficult than oxides thus the addition of oxidant is necessary. In this paper, oxidative leaching of mixed ore in NH3-(NH4)2SO4 solution using ammonium persulfate as oxidant under atmospheric pressure and relatively low temperature was investigated for the ...
Unlike mineral sulfide ores, iron ore does not provide an energy source (e.g., ferrous and sulfur compounds) for the oxidative growth of bioleaching microorganisms; however, iron-reducing bacteria, which gain energy by the dissimilatory reduction of ferric iron to ferrous iron, may be useful in upgrading iron ore .

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles .
