Gold Heap Leaching Process - Mineral Processing Plant ...

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 device and so on to separate gold

Heap leaching - Wikipedia

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. mo

Heap Mining Efficiently Leaches Lower Grade Gold from S

The biggest breakthroughs in heap leach mining for gold recovery have been in the development of methods for chemically desorbing gold from “loaded carbon”. Today, many options are available to the recovery plant designer and operator. Each method has advantages and disadvantages, which should be evaluated when deciding which process to use. These procedures must allow the carbon to be ...
