Extracting Copper Sulfide Ores

  • Copper Mining and Extraction Sulfide Ores

    The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to …

  • The Extraction of Copper - Chemistry LibreTexts

    Extracting of Copper from Other Ores. 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.

  • Copper extraction - Wikipedia

    Secondary sulfides – those formed by supergene secondary enrichment – are resistant (refractory) to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits. Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalc…

    If sulfide ores containing iron and copper are to be smelted, an understanding of both the iron and the copper systems is needed. Again, as in Figure 2.1.3 for the Cu–S–O system, the calculations are limited to oxidation by industrial oxygen so that the pressure of SO 2 will be about 1 atm., except where oxygen pressure is appreciable near the top of the diagram [ 3 ].

    Three different stages are involved when extracting copper from non-sulphide ores. 1. Over a very long time and on a vast scale, the reaction of the ore with a dilute acid (such as dilute sulphuric acid) produces an extremely dilute copper sulphate by solvent extraction. 2. a. By solvent extraction, the copper sulphate is concentrated. b.A fairly small amount of organic solvent containing a ...
