Grain size, oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery. 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.

Hydrometallurgical Recovery of Gold from Mining Wastes
11.11.2020 Generally, gold leaching using thiocyanate (0.01–0.05 M) occurs at a potential of 0.4–0.45 V, pH 1–3, in the presence of an oxidant like ferric ions (2–5 g/L) or peroxide. It has been shown that, under optimal conditions, a gold extraction yield of 95% can be achieved [ 21 ].
