Different methods of concentration of ore

metallurgy: Concentration of the Ore. When an ore has a low percentage of the desired metal, a method of physical concentration must be used before the extraction process begins. In one such method, the ore is crushed and placed in a machine where, by shaking, the heavier particles containing the metal are separated from the lighter rock

    When ore is processed (typically very close to the mine), it is ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a concentrate. At a molybdenum mine, for example, this concentrate may be almost pure molybdenite (MoS 2). The rest of the rock is known as tailings. It comes out of the concentrator as a wet slurry and must be stored near the mine
