1. Product
introduction
The product uses high quality apricot shell as raw
material, is produced throughhigh temperature steam
activation and refining. The activated carbon has the
characteristic of uniform granularity, high strength, good
adsorption, large adsorption capacity, easy deabsorption, etc. is
mainly used for separation and extraction of non-ferrous metal,
especially used to extract gold with heap-leaching method will have better effect, also used for
theextraction of gold tailings.

Introduction of
heap-leaching of gold
Heap-leaching of gold is heaping
thelow-grade gold or
tailings inbottom cushion
material, through recirculated spray of sodium cyaniding, to make the
the gold and silver dissolve
out.
The method has the
advantages ofsimple technology, easy operation, less
equipment, less power consumption, low investment, fast effect, low
production cost, and etc. Heap-leaping is used to
process0.**3g/t low grade ores,
the rate of the gold recovery is *0%****0%, even can achieve *0%.
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.
