Concentration Of Ore: Types, Procedures, Extraction - Collegedunia

Concentration of ore can be explained as a method by which gangue is separated from the ore of the metal.The process is also known as dressing or benefaction.Gangue is the combined name of the impurities like sand, clay, grit, etc. . Gangue needs to be separated because minerals are present in high concentration in its ore.

Concentration is also called “Ore dressing” or “Benefaction”.

Concentration: The metallic ores obtained from the earth’s crust also consists of impurities like organic matter, non-metallic compounds, and other rocky materials like clay, limestone etc. These impurities are collectively known as gangue or matrix. Removal of gangue particles from the ore is called concentration.
