After the gold-bearing ore undergoes crushing and grinding operations, the gold and gangue minerals are formed into monomers to dissociate, and then through roughing and beneficiation operations, the gold is extracted using the density difference between gold and gangue minerals.
The main equipment for reselecting gold is centrifuges, jigs and shakers.
The gold flotation process is suitable for processing fine gold particles and high floatability sulfide gold-bearing vein ore, polymetallic gold-bearing sulfide ore and carbon-bearing ore, etc. The flotation recovery rate of sulfide ore is 90%, and a few can reach 95%-97%; the recovery rate of oxide ore is about 75%, and individual can reach 80%-85%.
The cyanidation method is to soak the finely ground ore particles with sodium cyanide solution to make the precious metals enter the solution, and then use zinc powder to reduce precipitation, or use other methods to precipitate metals from the solution. It is an important method to extract precious metals such as gold and silver from ore. This method is especially suitable for processing ore with low precious metal content.
Heap leaching of gold ore is to crush low-grade gold ore to a certain size (or granulate) and pile it on a leak-proof bottom mat paved with materials such as asphalt, concrete or plastic cloth, and use low-concentration cyanide, alkaline solution, Solutions such as non-toxic solvents or dilute sulfuric acid are sprayed on the mine pile to dissolve the gold, and the gold-containing solution is infiltrated from the mine pile, and then the gold is recovered by methods such as activated carbon adsorption or zinc powder replacement precipitation.
Ore permeability is a decisive condition for the technical feasibility of pit leaching. Ore grade and material composition, ore body thickness and buried depth are important conditions for whether pit leaching is economically reasonable. For pit leaching, the leaching rate is closely related to the degree of ore oxidation and fineness. Generally, the finer the grinding fineness of the material, the higher the leaching rate. The advantages are low capital investment, short construction period, low production cost, and the recovery rate can reach 80-95%.
The zinc powder replacement process is used to treat gold-containing precious liquid after cyanide leaching. The principle is to use zinc powder as a reducing agent to replace gold and silver from the leaching liquid. There is also a zinc wire replacement process that uses zinc wire instead of zinc powder in the industry, and its operation process is similar to the zinc powder replacement process.
Amalgamation method is an ancient gold extraction method, It is mainly used for processing gold concentrate from sedimentary gold or vein gold deposit. The gold recovery rate of amalgament barrel will reach more than 98%.It has simple process,easy operation,small equipment investment,high gold recovery rate .This method is widely use in gold processing factory.This method is suitable for less copper,lead,zinc content and no sulfur gold mine.
The integrated placer gold washing plant:
Capacity: 3-500 tons/hour, It’s customized size;
It’s suit for Monomer gold recovery for placer gold and vein ore
Power: generator set or diesel engine. Customized according to the actual situation of the mining area.
Gold mine refers to gold ore or gold deposit (mountain). Gold ore is an aggregate of minerals with sufficient content of gold that can be used industrially. Gold mines are places where gold is obtained through mining operations, and are a certain scale of industrially usable gold ore accumulation formed through mineralization.
Our company has rich experience in design and construction of Alluvia/Deluvial/River gold ore processing industry.we have plenty successful project in Africa,South America.Southeast Asia,China and many other contries.
