ANTAM's gold and refinery business segment consists of gold commodity, silver and precious metals processing and refinery services. Gold and silver commodity of ANTAM was produced through mining activity and gold ore smelting to dore bullion. The gold ore mining is produced from two mining sites Pongkor, West Java and Cibaliung, Banten.The technology boom for developing pure gold continued with E.B. Miller’s process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill’s electro-refining process (introduced in Hamburg, Germany, in 1878). In fact, gold with purity of 99.99 percent is created using a combination of the processes.Processes based on direct chemical purification and recovery from solution as elemental gold can greatly speed gold processing and virtually eliminate expensive in-process inventories. Refining from scrap. The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction.Although most gold is produced from alluvial and other surface mining, or from underground reef mining, some gold is produced as a by-product when copper, lead, and uranium ores are refined. An estimated 30 percent of the gold in the U.S. is produced by these means. The exacting process of refining gold.
