: The chemical treatment of the ore for concentration is …
Hint: Concentration of ores is the removal of unwanted impurities (i.e., gangue or matrix) from the ore. After the ore is finely ground, it can be concentrated by many methods. When the concentration is done by treating the powdered ore with suitable chemical reagents which can selectively dissolve the ore but not the impurities, the process is called leaching. It is generally …
