Note: Until I added the questions in July 2015, I had always assumed (on no good evidence - never a good idea!) that chalcopyrite contained copper and iron both in the +2 oxidation state - but that may well be wrong. If it was true, then you can show that the sulphide ions are reducing Cu(II) to Cu(I). However, if the copper was in the +1 state originally, then …
ادامه مطلبThe four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

ادامه مطلبThe important ores of copper are copper pyrites ((CuFeS_2)), cuprite and copper glance. The copper ores are mostly found in the north of India. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air.
ادامه مطلب1. Introduction. Heap leaching is a low-cost, flexible hydrometallurgical process for recovering valuable metals from low-grade ores (Nosrati et al., 2012).In this process, the ore bed must be porous and permeable to permit flow of the leach solution (Lewandowski and Kawatra, 2009a).However, fine particles usually migrate into the …

ادامه مطلبThe main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.
