It takes  high  quality products of gold coconut shell as raw materials,  and refine from activated process and through  the wind converter selection, crushing, screening and other processing , it is high strength uniform size, well-developed porous structure,it is good adsorption material for the gold cyanide complex selection,it can be decomposed easily, and can be recycled for many times, repeatedly. It has a special precious metal adsorption, mainly for the CIP, heap leaching of gold extraction and separation of precious metals in the metallurgical industry, extraction. As in the smelting of gold, especially in CIP for leaching gold extraction process has an excellent effect.
