2013/09/17· Now we are looking for investors to invest in our new project of Small Gold Cyanidation plant that costs about 350,000.us$. The plant will be able to produce 25-35kg of gold per month.
When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
As most gold and silver in the Iwato ore are concentrated in the pores, leaching of coarse sized ore is expected to be possible. Laboratory tests and pilot plant tests of vat leaching for the Iwato ore were carried out using 0.15-8.0

2018/06/20· Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, …
Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores.
