2014-6-26 The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
More2011-3-9 I am trying to figure out the steps to smelt gold ore, which contains also silver, copper and platinum, into something I can sell. The ore has been assayed @ 60 ounces per ton of the above metals. The concentrations of each vary but the breakdown is approximately as follows: Silver = 23oz/ ton. Copper = 9oz/ ton. Gold = 19 oz/ton.

MoreLarge companies normally smelt gold on site to cut down on costs but cannot refine gold themselves. Smelting gold is accomplished by using high pressure, heat and various chemicals to breakdown the ore and melt the gold to separate it from the impurities. The gold must be heated to an excess of 1046 degrees Celsius or 2150 degrees Fahrenheit.
