Gold mining is the process of mining of gold or gold ores from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted.
ContactMiners from Sonoran Mexico had a technique for pulverizing gold ore that required no water for the initial stages of gold processing. Called the arrastre, this system consisted of an upright axle with large spokes. Horses or mules, hooked to the outside edges of the spokes, pulled them around and around.
