Grinding and Concentration of Conglomerate Copper Ore

 · The ore was crushed through ½-inch prior to grinding. Pieces of +½-inch copper were removed from the circuit by handpicking from the +½-inch return belt in the crushing circuit. Because of the small amount of coarse copper in the ore, no problems were experienced in crushing.
