Gold derived from nature usually in two forms of gold in the form of fine granules which are usually obtained by panning and gold derived from rocks containing gold called gold ore. To obtain gold ore required heavy equipment used to crush the stones because it is generally very hard. In addition to using heavy equipment are often done by blasting bombs to destroy rocks containing gold.
After the rock is crushed transported into gold ore processing plant by truck, but some companies use a series of runs like railroads and tire cord. Tire cord is a tool that resembles a hanging rail transport, usually across a steep ravine towards the lower part. One of the tools used to drill the walls of the mine to search for gold ore as shown in the picture.
Gold mines is processed by the company whether foreign or domestic company is derived from rock gold gold or gold ore. High-quality rock is rock that contains about 30 grams of gold per ton of rock gold, but usually a mined rock containing at least the gold content over 8 grams per tonne of gold ore.
For the gold obtained by panning generally mined illegally by people typically use mercury to precipitate fine grains of gold in water or with mud. Gold is obtained in this way are usually sold directly without being processed first.
