Gold dressing process

Different gold nature using different mineral processing technology

Recommended solution

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.

  • Gold CIL process
  • Gold flotation process
  • Gold cyanide process
  • Zinc powder replacement gold extracting process
  • Extraction of gold by heap leaching
  • Gold gravity separation process
  • Gold CIL process
    Active carbon adsorb the liquid state gold in alkaline cyaniding solution
    Process description:

    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 >
    Application:

    The gold CIL process is mainly used in the oxide ore which has low grade of silver , its more economize and has more benefit .

  • Gold flotation process
    Process high flotability gold sulphide ore.
    Process description:

    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 >
    Application:

    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...

    Ecuador 300 d/t gold flotation
  • Gold cyanide process
    Use cyanide as lixivium to extract gold.
    Process description:

    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 >
    Application:

    Gold mine in flotation process or mercury amalgam，tailings in gravity process ,oxide mineral with pulp and gold extraction plant with cyaniding agitation .

  • Zinc powder replacement gold extracting process
    Add zinc into the pregnant solution containing gold, the gold and silver will settle in gold mud via chemical reaction.
    Process description:

    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 >
    Application:

    It mainly include medicating & aeration, agitation leaching, backwashing, zinc powder replacement, gold mud smelting, tailing filter pressing, swage treatment, etc.

    Typical cases
    Myanmar 1000t/d CIP plant
  • Extraction of gold by heap leaching
    Spray the low concentration cyanide or thin vitriol etc. on stock heap to solve the gold, then use other way to recovery.
    Process description:

    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 >
    Application:

    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 >
  • Gold gravity separation process
    Cyanidation-carbon adsorption process is widely used in gold cyanide extraction process.
    Process description:

    The gravity separation process create a comfortable loose layer and separation condition in virtue of integrating...

    Detail >
    Application:

    gravity process is a traditional and basic method to separate gulch-gold , and it`s the most effective process...

Laboratory
The origin of mining process

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.
