4 Factors Affecting Gold VAT Leaching Process

The size and shape of the gold particles exposed to the ore will affect the gold leaching rate. The larger the gold particle size, the slower its dissolution rate. Therefore, gold ore should be pre-ground before cyanidation, so that gold particles are fully exposed, which will improve the vat leaching rate and shorten the vat leaching cycle.

The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 2014· Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Vat Leaching of Finely Crushed Gold Ore

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, ample contact with strong and weak
