What is gold?
Gold is a powder of gold, but it is full of impurities other than gold, also known as a black stone similar to salt or gunpowder so that it shines when exposed to the sun directly, or when the light on a dark place, and can be identified if Or not by placing it in water, gold and silver are deposited in the bottom of the pot and impurities float on the surface.
To separate gold from raw material
The methods of extraction of gold vary depending on the type of sediment. There are two steps to get gold: how to get the raw materials, and the process of separating the gold material from the raw material through the transfer of raw materials to the mills to be separated.
In prospecting for gold, these processes are carried out at the site of the sediment, where mineral sediments or rocks are excavated underground in the same way as coal mining. The prospectors follow the metal veins by digging a vertical path inside the earth and some materials are found on the surface of the earth Through the cracking of rocks using blasting, then take rocks that contain gold and sent to the mills to separate gold from rocks and impurities, or through hydraulic pumping by pumping water rushing towards the rocks that contain gold, it is swept into vessels with grooves to reserve Gold.
Another way is through the crane, which is an energy-digging machine that has several buckets installed on a vessel. Each bucket has a capacity of about 0.2 m. These buckets are lowered by the lever and rotate in a circular way to lift The gravel is from the bottom of the river, and the crane has several devices that separate the gold from any other materials stuck with it.
There are three ways to separate gold from raw materials or water:
1. Floating mode : This method is after the detonation and drilling and after the discovery of gold ore, where the extraction of gold by doing the grinding of the ore and its screening and then treated by buoyancy or float to separate the metal.
2. Cyanide method : It is a sophisticated and modern methods, is done by spraying the raw material solution cyanide, which melts the gold and is passed on the granules of carbon are located in the columns of electricity to attract gold.
3. Carbon fiber method : The cyanide is also used by mixing the raw material crushed into the water in order to get the ball and then dissolve in the cyanide solution and then add the carbon particles of the ball to float gold ions on the surface and collected and then removed carbon particles from the lava and then placed in the solution of cyanide hot and Extracting gold from carbon.
