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.

How Is Aluminum Extracted From Its Ore?

Apr 17, 2020To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash. This mixture is placed into a digester, where it is heated under steam pressure. Caustic soda is added, which dissolves the alumina from the ore. The other impurities are left as solids. After this, a filter separates the solids from the solution. Get price
