    Several steps are involved in the extraction of pure metal from ores. Below is given a flow diagram of various steps involved in extraction of metals – Concentration of Ores . 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
