Gold extraction

The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed.The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore.The gold could not be extracted frompound with any

Gold

Gold is a chemical element with the symbol Au from Latin: aurum and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.Chemically, gold is a transition metal and a group 11 element.It is one of the least reactive chemical elements and is solid under
