2013-1-2 The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.

2005-7-1 Fig. 2 shows the leaching of the slimes using the former standard plant leaching conditions (pH 11, 2.4. g/L NaCN, 9 ppm DO) and the new leaching regime which included an 8 h pre-conditioning with 20 kg/t lime followed by a cyanidation at 1.2 g/L lime, 4.6 g/L NaCN and 25 ppm DO.. The new leaching conditions significantly increased the gold leaching kinetics and the overall gold extraction.

2004-2-1 The plant processes a blend ratio of up to 1:1 of underground sulphide ore and open pit ore at a rate of 115 tph. The gravity circuit recovers the fine free gold (P 80 ≈75 μm), 10–20% of the total amount of gold inputted into the plant, to produce a gravity concentrate with a fine gold purity of between 75% and 80%.Fig. 1 illustrates the leaching and adsorption circuit schematically ...

Six Factors Affecting Gold Leaching in Cyanide Leaching . 5. Leaching time. Gold cyanide leaching is a relatively slow process, the leaching time is over 24 hours generally, and the gold leaching rate is improved with the extension of leaching time, but the gold leaching speed is reduced corresponding, and finally, the gold leaching rate tends to a limit value.

2009-8-27 Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide. The leaching of gold can be conveniently represented by the Elsener equation: [1] Although air agitated leach tanks were commonly used in the industry, mechanically agitated reactors are preferred due
