Cyanide Leaching Mining SGS. Heap Leaching. 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.

Heap leaching

Heap leaching

Although heap leaching is a low cost process, it normally has recovery rates of 60 70%. It is normally most profitable with low grade ores. Higher grade ores are usually put through more complex milling processes where higher recoveries justify the extra cost. The process chosen depends on the properties of the ore. The final product is cathode copper.
