Feb 28, 2016 Gold content (oz t) = gold weight (mg) x [29.166 sample weight (g)] Gold Refining Book. For example, if the fire assay reported 0.1 mg of gold and the initial weight of sample was 20 g, the gold content is 0.14583 oz t or 4.54 g t. Smelting-Ore-in.
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.
Feb 28, 2016 Intensive cyanidation is a good option, but obviously, the material can be sent to the leaching process employed to treat the raw ore. Gold and silver recoveries are between 99.5 to 99.7 . Although slag production weight is variable, a typical operation can generate 10 kilos of slag per 1000 oz of gold.

Aug 07, 2013 In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, it’s possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.
