1. Product introduction

There are three categories of gold activated carbon as coconut shell gold activated carbon, apricot gold activated carbon, wood based columnar gold activated carbon. They have the advantages of uniform granularity, strong adsorption capacity, high abrasion resistance, which are suitable for gold mining and production of modern ore, are mainly used to extract gold with heap-leaching or carbon-in-pulp method, to separate and extract of precious metals in the metallurgical industry.

 2. The usages of activated carbon

Activated carbon is widely used in all aspects of industrial and agricultural production, such as petrochemical industry non-alkali deodorization (refined de-mercaptan), ethylene desalination water (refined packing), catalyst carrier (platinum, palladium, rhodium and etc.), water purification and wastewater treatment, the power plant water treatment and protection in electric power industry, chemical catalyst and carrier, gas purification, solvent recovery and the decolorization and refining of oil in chemical industry, beverage, wine, MSG liquor in food industry and refining, decolorization of foodstuff, gold extraction and tail liquid recovery in gold industry, wastewater treatment, waste gas and harmful gas treatment, gas purification in environmental protection industry, and related industries cigarette filter, wood floor moisture proof, adsorbing odor, automotive gasoline evaporation of pollution control, the preparation of various impregnanting liquid and etc. Activated carbon will have a good development prospect and broad markets in the future.

 3. Gold refining process

(1) Extracted gold by amalgamation

The extracted gold by amalgamation is an ancient craftsmanship, which is not only conveniency, but also economical, and suitable for recycling coarse grained monomer gold. Many gold mines in China still follow the above method. Along with the development of gold production and science and technology progress, the method is gradually improved and developed. Because the environmental protection requirements are increasingly strict, some mines have cancelled mix mercury homework, and which is replaced with gravity separation, flotation separation and cyanide process of exacting gold. In the gold production, according to ore properties mix mercury and flotation separation combination process instead, the recovery rate improves 7.81% (amalgamation rate is 64.6%), tailings grand can from 0.74g/t drop to 0.32g/t.

The key of extracted gold by amalgamation is how to take protective measures to eliminate mercury toxic pollution.

 (2) Extracted gold by cyanidation

The extracted gold cyanidation is the main method to extract gold from ore or ore concentrate in modern. The method has some base programs as follow roasting-cyanide leaching, leaching pulp of washing filtering, the gold extraction from cyanating solution or roasting-cyanide pulp, finished product smelting and etc. The gold mines existing cyanide factories are basic using two kinds of exacting gold process, one is so-called ordinary cyanidation to exact gold, which is using thickener to carry out continuous countercurrent washing, using zinc powder to replace precipitation to recycle gold. The other is no-filtering cyanidation CIP process, which is without filtering and washing, directly using activated carbon to adsorb and recycle gold from roasting-cyanide pulp.
