The Mined copper ore is initially crushed, milled and concentrated by ore beneficiation process into a fine, gray powder called copper concentrate. If the nature of ore is sulphide, froth floatation process is adopted to do the beneficiation wherein the 1 % copper containing ore is converted to more than 25 % copper containing concentrate.
