2.4.1.2 Dry beneficiation. Dry beneficiation has two important advantages—saving water, a valuable resource, and no tailings pond and subsequently, no leaching of the trace/toxic elements into ground water. In dry beneficiation of coal, coal and mineral matter are separated based on differences in their physical properties such as density, shape, size, luster, magnetic …

Initially, copper ores, usually chalcopyrite, are mined and crushed into a fine powder. The crushed ore undergoes concentration through froth flotation, where copper minerals are separated and collected. For sulfide ores, the concentrated ore is roasted to remove impurities. This is followed by smelting, where the ore is heated with silica and ...
