Gold Heap Leaching Process

Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold-containing solution is leached. Then used the method of carbon adsorption, zinc powder displacement ...

Method of Gold Separation--1. Gravity Separation

2015-12-3 · Method of Gold Separation--1. Gravity Separation. The gravity separation working principle: Separate minerals according to the different relative density of the mineral (usually called specific gravity). The mineral particles of different density are treated by moving medium (water, air and heavy liquid) with the hydrodynamic and mechanical forces.
