The process of Gold mining begins when geologists take ore samples to determine the best places for companies to mine. The mining process can begin once the mining engineers know where gold is located and what other materials surround it. The gold is mined with open-pit mining techniques if the gold is located close to the surface.
Gold that’s located farther below the surface is collected with underground mining methods. Large pieces of ore are made into smaller pieces, and then the sand grain-sized pieces are mixed with a cyanide solution to create a watery, mud-like mixture.
However, gold is readily dissolved in a number of solvents, including oxidizing solutions of hydrochloric acid and dilute solutions of sodium cyanide. Gold readily dissolves in these solvents because of the formation of complex ions that are very stable.
Gold melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimeter) has made it amenable to recovery by placer mining and gravity concentration techniques. With a face-centered cubic crystal structure, it is characterized by a softness or malleability that lends itself to being shaped into intricate structures without sophisticated metalworking equipment. This in turn has led to its application, from earliest times, to the fabrication of jewelry and decorative items.
With more years of experience in the processing of gold ore, we have accumulated a wealth of professional knowledge and we have done many successful projects. For these years, we’re dedicated in providing professional gold extraction solution for different type of gold mine.
