Different gold nature using different mineral processing technology
Gold content is very low in ore. To extract gold, need crush and grind ore and use mineral processing technology to pre concentrate or separate gold. For gold dressing, the gravity separation, flotation and cyaniding are widely used. The CIL are widely used in Africa.
Cyanidation ---carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution .
Detail > The gold CIL process is mainly used in the oxide ore which has low grade of silver , its more economize and has more benefit .
Detail > 
Flotation is a method that is widely used in gold ore processing plant to process the rock gold , commonly used in dealing with highly floatable sulfide minerals containing gold ore. Flotation...
Detail > Flotation is suitable for processing the gold-bearing sulfide ore which with fine and floatable gold particles , during flotation , sulfide ore act as the carrier of gold...
Detail > 
Chemical property of gold is very stable , but it has a character , when it is in the editpotassium cyanide solution , and filling the air , gold will become soluble cyaniding liquid .
Detail > Gold mine in flotation process or mercury amalgam，tailings in gravity process ,oxide mineral with pulp and gold extraction plant with cyaniding agitation .
Detail > 
It is an old cyanidation process. Firstly, add cyanide into ore to leach out minerals, then separate the solid and liquid. Add zinc powder or zinc wire into the liquid and the gold and silver will...
Detail > It mainly include medicating & aeration, agitation leaching, backwashing, zinc powder replacement, gold mud smelting, tailing filter pressing, swage treatment, etc.
Detail > 
Pump leaching is a process that grind gold mine with low grade to a certain particles , heap up on the leakage-proof bottom mat that concreted by pitch , concrete or plastic cloth , spray the low...
Detail > Heap leaching is a process that use to treat the gold mine with low grade , cause it`s process simple , easy operation , low energy consumption , investment saving...
Detail > 
By the way of continuously technology research and development, design and research institute get remarkable achievement in gold mineral processing technology, at the same time, the research achievement in refining of nonmetal, various oxide ore recovering, comprehensive utilization etc. is also in international first-class level.
Detail >The oxide species of Jinpeng Laboratory are adaptive , high speed oxidation , the refractory ore after oxidation , the recovery rate could be 92%-95%，increase 40%-70% recovery rate than cyanidation , this is a break for refractory ore processing . over the years, constantly create new technology, fill the domestic blank, and won numerous domestic awards.
