    Some minerals require a physical and/or chemical process to remove them from the ore. Large rocks containing minerals need to be crushed and milled. The valuable minerals are then separated from the rock using a variety of physical and chemical separation methods.

  • Concentration of Ores: Hydraulic Washing, Froth Flotation

    Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of minerals and gangue.
