    Ore is still being extracted from Broken Hill, which has been the largest producer of lead-zinc-silver in Australia. The wealth generated by mining the Broken Hill ore allowed The Broken Hill Proprietary Company Limited to prosper and, although it no longer has an interest in the deposit, its successor, BHP Billiton has become one of Australia's largest companies.

    Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.

To quote Agricola (pp. 220-223): "The method of assaying ore used by mining people, differs from smelting only by the small amount of material used. Both processes, however, are carried out in the same way, for

    The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead. The local variety of Galenite is silver-bearing and is known as Argentiferous Galenite (formula (Pb.Ag)S ) and the lead obtained from this ore contains just a small percentage of silver - from 0.8% up

    The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace. The furnace must reach temperatures in excess of 1064 degrees Celsius, in order to elevate the gold above its melting
