Jun 29, 2018· In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S to give copper metal. In this process, Cu 2 S behaves as reducing agent.
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. During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulfide and cuprous sulfide.
· copper extraction from its ore: 1915 . Copper extracted from ore classed as copper bearing (copper, copper-lead, and copper-zinc ores), and total production of copper from all sources in 1915. Considerable copper was recovered from old slag and ores not classed as copper ores.
Extraction of copper from cuprous oxide [copper(I) oxide] Copper is extracted mainly from copper pyrites (CuFeS 2). The extraction involve the following steps given in flow sheet.
The method works due to the iron being more reactive than copper, also the copper is more desirable than iron. Why should we recycle metals? Because extraction of then uses limited resources, and is expensive in terms of energy and it effects the environment

May 22, 2012· leaching, the recovery of copper from the drainage water of mines, as a method of the extraction of minerals, it was well established as early as the eighteenth century, but until about 25 years ago miners did not realize that bacteria taken an active part in the process. (A) as a method of the extraction of minerals, it was well established.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
The labile copper(II) system formed by interacting with both the water and the IL cation component has been characterized by cyclic voltammetry as well as UV−vis, Raman, and 1H, 13C, and 15N NMR spectroscopies. The extraction process does not require the addition of a complexing agent or pH control of the aqueous phase.
Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper. This is similar to the electrolysis that is done in a school lab.
