copper processing from extraction

Extraction Of Copper Mining, Concentration,

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister Copper;

The Extraction of Copper - Chemistry LibreTexts

2021-6-7  Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper (II) sulfate solution. Concentration of the copper (II) sulfate solution by solvent extraction.

Copper extraction by wet chemical method -

2018-1-1  Currently the extraction of copper is performed using a pyrometallurgical process that involves the use of electricity as well as coal, both of which are expensive. The use of fossil fuels in extraction produces carbon dioxide which contributes to global warming. The other method used is solvent extraction followed by electro-winning (SX-EW).

GROWING ROLE OF SOLVENT EXTRACTION IN COPPER

2008-9-23  At present, the most up%to%date problem is application of solvent extraction for copper processing from sulphide ores. The success of SX plants in the copper recov%ery system results from easy leachability of oxide ores, while the main obstacle for application of hydrometallurgy for sulphide ores processing is difficulty of their leaching, relevant to scarce solubility of copper sulphides, particularly chalcopyrite. Therefore the efforts of scientists are focused mainly on finding the best efficient leaching method and then liquid%liquid extraction
