    The Extraction of Copper Chemistry LibreTexts

    21-08-2020· The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (CuFeS2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

    copper extraction and purification chemguide

    Copper can be extracted from non-sulphide 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 sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction.

    Extraction Of Copper Mining, Concentration, Smelting

    The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as iron silicate slag. Most of the sulphur in Chalcopyrite turns into Sulphur dioxide (SO 2 ).

    Copper extraction Wikipedia

    Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper

    A rapid field method for the determination of readily-extractable copper in soil and sediment has been developed for use in geochemical prospecting. A 0.2 g sample is treated with 1 ml of cold 6 N hydrochloric acid for 30 seconds; the copper that is extracted is estimated by means of 2,2'-biquino-line in an isoamyl alcohol extract. A sensitivity of 1 ppm is obtained when a 0.2 g sample is used.
