Variants include vat leaching (in tanks), agitated leaching (with stirring), and heap leaching (more on that later). Recovery rates often hit 70-90% for free-milling ores, where gold particles are easily accessible. Why it works for small-scale mining: It's widely understood, delivers high yields, and scales to modest operations.

In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the SX/EW plant. The electrowinning of copper requires considerably more electrical energy than does the electrorefining process - an average of about 8 MJ/kg for electrowinning vs about 1.5 MJ/kg for electrorefining.
