Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from lowgrade ore.

Mining Gold Equipment: What Tools Do I Need For Gold Mining? The type of tools that you will need for gold mining depend a great deal on the type of mining that you have in mind. If you are just out for a day of entertainment to chance your arm in one of the free to prospect rivers then you will need only very basic gold prospecting supplies.
Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.
Coal mine An area of land and all structures, facilities, machinery, tools, equipment, shafts, slopes, tunnels, excavations, and other property, real or personal, placed upon, under, or above the surface of such land by any person, used in extracting coal from its natural deposits in the earth by any means or method, and the work of preparing ...
Coal processing, mainly for reducing ash and sulfur contents in the mined raw coal, requires a subset of processing technologies. Some problems in coal processing arise from the way the sulfur and ash are bonded and the need to keep the water content in the cleaned coal low.
What tools and equipment did the miners in the gold rush use? ... For placer mining, the miners mostly used: picks and shovels (to loosen and gather goldbearing dirt for processing) gold pans
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation. Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped.
The Klondike Gold Rush, also called the Yukon Gold Rush, the Alaska Gold Rush and the Last Great Gold Rush, was an attempt by an estimated 100,000 people to travel to the Klondike region of the Yukon in northwestern Canada between 1897 and 1899 in the hope of successfully prospecting for gold.

However, there are chances that diamonds form from coal, in case of subduction. Conversion of coal to diamonds is a natural process that takes millions of years. Even though there are carbon atoms in coal, the amount of impurities are so high, that it takes millions and millions of years for the coal to transform to its nearly purest form ...
