Two models were generated from the data to predict gold extraction and thiosulfate consumption as a function of the leaching parameters. The models predicted a gold extraction of 67 pct and reagent consumption of 2 kg S2O3178; /mt ore at 0.25 M S2O3178; , 0.0014 M Cu178;+, 0.27 M NH4OH, 0.00625 M SO3178; , and leaching for 16 h.
Gold extraction. Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques .

Nov 21, 20080183;32;The next process of gold extraction from Hydrometallurgy route is Leaching. There are reagents that can be used to gold leaching process Mercury (Hg), Cyanide (CN ) usual as KCN or NaCN, Thiosulphate (Na2S2O3), and Thiourea. Reagent vote for leaching process depend on 1. Kind of Ore 2. Grade of Gold in the Ore 3. Cost 4. Material Handling 5.
Types of ore. Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as color) embedded in rock minerals.
Starting with ore containing 1.4 g/t of gold, it has been possible to generate a sulphide concentrate with 6.1 g/t of gold by physical beneficiation of the ore through froth flotation. Thiourea leaching of this flotation concentrate after pressure, pre oxidation has resulted in gold extraction of 98%, with an overall gold recovery of 74%.
changes in the metallurgical techniques for gold extraction since the introduction of the cyanide process (cyanide leaching or cyanidation) by McArthur and Forrester in 1887 . A basic flowchart for the recovery of gold from its ore is provided in Figure 1. Figure 1 Basic flowchart for gold recovery.
Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earths crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions nuggets of native gold weighing up to 50 kilograms are foundthe largest having weighed 92 kilograms. Native gold invariably contains about 0.1 to 4 percent silver. Electrum is a gold silver

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 pyritic ore. The gold could not be extracted from this compound with any of the then available chemical processes or technologies. In 1887, John Stewart MacArthur, working in collaboration with brothers Dr. Robert and Dr. William Forrest for the Tennant Company in Glasgow,
