Aug 20, 2020· Many methods of extractive metallurgy may be applied to get a pure metal from its naturally occurring ore. First ores must be concentrated and separated from their earthly impurities. Concentration of ores may be achieved by froth flotation in which an ore is contained in a froth that floats at the top of a water vat.

Copper Mining and Production Processes Explained

Concentration of ore is a step involved in the process of extraction of metal from its ore. Unwanted rocks and grit are eliminated from mineral ore in this process. Hydraulic washing, froth floatation process, magnetic separation and chemical separation are some of the techniques used for concentrating or purification of ores.
