Heap Leaching, Heap Leaching Consulting, Heap Leaching of

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 from the liquid.

Heap Leach FL

In Heap Leaching, precious metals are extracted from raw materials using chemical reactions that absorb and separate out waste materials, leaving valuable ore for further processing. In this process, the materials are placed on a specialised liner, and the chemical catalysts are added via a drip system. At FL, we provide industry leading Heap Leach technologies and services.

Vat leaching can be considered when an ore body does not have the grade or quantity to be a candidate for normal agitation leaching, and as an alternative to heap leaching. At a location where there is excessive rainfall, such as more than 120 in./yr, or even a short and intense rainy season on the order of 50 in., the solution in heap leaching can become seriously diluted.

Cyanide Leaching Mining SGS

Heap leaching facilitates the profitable extraction of gold from very low grade ore. Prior to heap leaching, either run of mine (ROM) or crushed ore is heaped into structures 10 to 20m high that are stacked on an impermeable layer. A dilute cyanide solution is sprayed on the heap, percolates through the pile and dissolves the available gold.
