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.

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

The type of process utilised to extract gold from the ore body is vastly determined by factors such as: the mineralogy of the ore and the degree of liberation of gold particles. The raw ore body is crushed and ground in the attempt to liberate/free as much gold, which could be separated either by a chemical, physical or surface based process.

Gold grinding process. Grinding also known as milling, pulverising or comminution, is the process of reducing gold materials to powder or very fine particle size. Gold grinding process is different from crushing or granulation process reducing the raw material to a rock, pebble or grain size.gold grinding is an integral part of gold mining process.

Gold electrolysis requires small amount of chemicals and labor. It is, in fact, environmentally friendly. However, it is a very expensive procedure because a permanent stock of gold is required to run the electrolytic process. Take for instance, for every gold produced through this method, 20% of it is lost on the anode.

The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing. The crushing is effected by stone-crushers, rolling-mills, and stamp-mills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles." In California hydraulic jets are employed to

The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you’re able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it''s hazardous to both your health and the environment to use them.

Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 B.C. , when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.
