A recent review (Kappes, 1998) concluded that for a "typical" Nevada-type ore body with ore grade of 3.0 grams gold/tonne (0.088 oz/ton), the mill recovery would have to be 21% higher than the heap leach recovery to achieve the same return on investment - and this is very seldom the case.

Briefly stated, gold heap leaching is a hydrometallurgical process designed to treat amenable low-grade gold ores that contain roughly 0.5 gram per metric ton (g/t) gold to 1.5 g/t gold (Marsden and House, 2006; Wong Wai Leong and Mujumdar, 2010). The ore is stacked by various types of equipment
Some other key drivers in flowsheet selection at the hashing stage are: Supergene weathering. This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold …

At this time, the stamps are the heaviest in use in the country. The ore is taken from the mine and crushed to a suitable size in an Allis-Chalmers gyratory crusher, carried to the storage bin in an ore car. Eventually, a 4 ton ore car is hauled up a tramway and ore stored in a second bin at the mill. This bin feeds direct to the stamps."
