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 Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of ...

12.3 Primary Copper Smelting

The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves, metallic impurities precipitate and form a sludge. Cathode copper, 99.95 to 99.96 percent pure, is then cast into bars, ingots, or slabs. 12.3.3 Emissions And Controls Emissions from primary copper smelters are principally particulate matter and sulfur oxides

Innovations: Introduction to Copper: Mining & Extraction

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.
