vat leaching | industrial process |…

With ores of higher gold content ( i.e., greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced. The huge heaps...

Agitated Tank Bioleaching - MINTEK | MINTEK

The most common cause of refractoriness is the association of the gold with sulfide minerals such as arsenopyrite and pyrite, by physical lock-up in the sulfide grains or by substitution in the sulfide lattice. This results in poor recoveries (as low as 10 to 20 per cent) by direct cyanide leaching. Several process routes are...
