Extraction of Gold

The so-called " brown gold " is formed by the action of nitric acid on an alloy of gold and silver containing 20 per cent, of gold. The silver dissolves, leaving the gold as a brown, spongy sheet, reconverted at 1040° C. into ordinary gold. The brown form (β) differs from ordinary (α) gold in density and magnetic properties.

Parting metallurgy Britannica

Parting, in metallurgy, the separation of gold and silver by chemical or electrochemical means. Gold and silver are often extracted together from the same ores or recovered as by-products from the extraction of other metals. A solid mixture of the two, known as bullion, or doré, can be parted by boiling in nitric acid.The silver is dissolved as silver nitrate, leaving a residue of gold that

Gold parting Wikipedia

Separation of gold from silver was not practised in antiquity prior to the Lydian Period (12th century BC to 546BC). Material from Sardis (in modern Turkey) is evidence of the earliest use of gold and silver parting in the 6th century. Literary sources and the lack of physical evidence suggest that gold-silver parting was not practised before the mid first millennium BC.

Gold extraction Wikipedia

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 from this compound with any
