Introduction of heap-leaching of gold
Heap-leaching of gold is heaping the low-grade gold or tailings in bottom cushion material, through recirculated spray of sodium cyaniding, to make the the gold and silver dissolve out.
The method has the advantages of simple technology , easy operation, less equipment, less power consumption, low investment, fast effect, low production cost, and etc. Heap-leaping is used to process 0.5-3g/ t low grade ores, the rate of the gold recovery is 50% ---80% , even can achieve 90% . So the heap-leaching makes many small gold, ore tailings, low grand ore, or waste stone can be economic recovery, which were regarded as no economic value.
