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.

Ore - Wikipedia

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.

Concentration of Minerals Article about Concentration of ...

The results of mineral concentration are two main products: the concentrate and tailings. In some cases (for example, in the concentration of asbestos or anthracite), the concentrates differ from the tailings mainly in the size of mineral particles. If an ore contains several useful components, several concentrates are produced from it.
