4 Factors Affecting Gold VAT Leaching Process

Gold vat leaching process is currently widely used in small-scale gold mines, because of a series of advantages including high recovery rate, strong adaptability to ore, low cost and simple process. The basic principle is first to leach the gold from the ore with cyanide solution containing oxygen, and then to extract the gold from the leaching solution with zinc powder or zinc wire.

COMPARISON OF CYANIDE AND THIOSULPHATE LEACHING FOR

Before leaching the gold, ore must be crushed and grinded into small particles, usually particle size varies between 30 and 180 μm. Free milling ores are ready for leaching after crushing and grinding whereas refractory ores need pretreatment. It is important to pretreat a refractory ore before leaching to achieve better gold extraction.

How to recover gold from cyanide solution, Learn

But we can assure you, gold recovery through cyanide can be done on a small scale also both chemically and electrolytically, but great care should be taken as cyanide is poisonous in nature. If one has to use cyanide process for gold extraction, never use laboratory grade always use commercial grade and use sodium cyanide instead of potassium cyanide that is less risky.
