metallurgy: Concentration of the Ore Infoplease

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 particles by gravity.

Ores and Minerals Introduction, Extraction

Before applying all these methods of extraction of metals according to their reactivity, concentration of ores is done. Ores are found in nature with many impurities such as rock particles, sand and other impurities. These impurities in an ore are called matrix or gauge. The removal of matrix or gauge from the ore is called concentration ore.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
