A description of the agitation leach plant used for treating gold-copper ores at cyanide heap leaching to produce a pregnant leach liquor, from which gold was.
Heap leaching applies often to low-grade ore. The processing plant stacks the ore in a heap on an impermeable liner. Stacking is often preceded by a crushing
Ore is heaped onto open-air leach pads with a base of asphalt or impervious is known as the 'pregnant pond', from which it is pumped to the recovery plant.
