Two (2) major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.

Sometimes the ore is very deep, which is often the case with diamonds or gold ore. In these cases mine shafts go vertically down and side tunnels make it possible for the miners and equipment to reach the ore. A structure called the headgear is constructed above the shaft and controls the lift system into the vertical shaft.

When gold is extracted from the earth, it is often attached to a variety of other minerals. A gold nugget, for example, is likely to have a purity of just 70 to 90%. In many cases, gold occurs in low-purity ore in the form of flecks or fine grains. Vast quantities of soil or sediment must be processed to find tiny quantities of gold.
