    Ores and Minerals

    First ores are crushed and grinded and then gauge or matrix is removed from the powdered ore. This is called concentration of ores. Ores of highly, moderately, and low reactive metals are 1 st concentrated. This step is common for ores of all types of metals. It is carried out by various methods depending upon the nature of the ore.
