How to Fix Agitator Mixer Problems in a Gold Leach Circuit

06-10-2020  A cyanide leaching circuit usually consists of large agitated tanks for mixing mineral slurry with cyanide in order to extract gold. Typically, the slurry consists of 30-40% solids by weight with the solid particles being less than 100 microns (0.1mm) in size. Air or oxygen is often bubbled through the slurry to improve the leaching reaction.

Gold CIL CIP Gold Leaching Process Explained CCD

02-01-2013  Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. 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 ...

29-07-2013  Vat leaching can be considered when an ore body does not have the grade or quantity to be a candidate for normal agitation leaching, and as an alternative to heap leaching. At a location where there is excessive rainfall, such as more than 120 in./yr, or even a short and intense rainy season on the order of 50 in., the solution in heap leaching can become seriously diluted.
