4. Vat-Leaching Process Vat leaching can be described as leaching in a bathtub inside a building. In Vat leaching the ore usually after size reduction either as a finely crushed or a coarsely ground and de-slimed is manually loaded into the vats. Vats are tanks built by bricks, cement and sand may be rectangular or circular with a partial filter floor. . Picture 1 and 2 shows types of vats ...

Percolation Heap leaching, see Mular et al. pp. 15711630, loc. cit. is very widely applied to the ores of copper and precious metals, but percolation is also conducted on a smaller scale in batch tanks or vats and in continuous or dump extractors. In the heap leaching of low-grade oxidized gold ores, for instance, a dilute alkaline solution of sodium cyanide is distributed over a heap of ...
Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.511 to ensure minimum loss of cyanide as hydrogen cyanide.
Oct 18, 2019 The agitation leaching method is to concentrate the slurry, obtained after grinding and classifying of the gold-containing ore, to a suitable concentration, place it in a leaching tank, add a cyanide solution, and aerate to carry out leaching. The main equipment used in the agitation leaching process is a cyanide leaching tank.
Immense amounts of solution and solids are associated with a vat leaching circuit, owing to the very low concentrations of gold in the ores. In order to eliminate the huge capital costs associated with the purchase and installation of solidsliquids separation equipment, techniques have been developed that circumvent the entire separation process.
