Extracting Gold - HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

METHODS USED TO IDENTIFYING MINERALS

The hardness of a mineral can be measured by its resistance to scratching or abrasion. The Mohs scale is a set of 10 common minerals chosen for comparative hardness. The minerals are arranged in order of increasing hardness; each mineral will scratch all that precedeit, and be scratched by all that follow it. The Mohs scale is as follows:

mineral - Classification of minerals | Britannica

Metals. Gold, silver, and copper are members of the same group (column) in the periodic table of elements and therefore have similar chemical properties. In the uncombined state, their atoms are joined by the fairly weak metallic bond.These minerals share a common structure type, and their atoms are positioned in a simple cubic closest-packed arrangement.

Cleavage of Minerals. A cleavage plane is a plane of structural weakness along which a mineral is likely to split smoothly. Cleavage thus refers to the splitting of a crystal between two parallel atomic planes.
