Today, chalcopyrite (CuFeS 2) is the most frequent source of copper ore, accounting for around fifty percent of copper production. Copper Mining. Mining is the initial phase in the extraction process. Copper ore must be extracted using either open-pit or subterranean techniques.
Chalcopyrite is of great economic importance since approximately 70% of global copper reserves are present in this mineral [].Traditionally, the main technology for copper extraction from its ores and concentrates was pyrometallurgy, but the gradual depletion of rich ore deposits and growing environmental concerns over …
A conceptual flowsheet is proposed, where chalcopyrite concentrate can be extracted by a leaching–grinding process and copper can be recovered by a solvent extraction–electrowinning circuit.
Copper can be directly extracted from the chalcopyrite and concentrated ore. Chalcopyrite-associated minerals contain copper (Cu), iron (Fe), zinc (Zn), and Sulphur (S). Chalcopyrite is one of the most stable minerals among sulfide ores due to its complex structure (face-centered tetragonal lattice) [1] .
A quantity of ore consist of 90% (by weight) chalcopyrite mineral with a composition of CuFeS 2.The rest is inert quartz, SiO 2.The ore is roasted by heating it in oxygen at 800 o C.
