Three ways for gold ore processing : 1.Gold cil & cip 2.gold flotation 3.gold Gravity. please see the contents below：
1.Gold ore CIL & CIP process
Gold CIL (Carbon in Leach)leaching process, namely Carbon leaching extraction, it is a process of adding activated Carbon to the slurry and simultaneously leaching and adsorbing gold. This process including leaching pulp preparation, cyanide leaching, activated carbon adsorption, the electric shock to get gold mud, to take off the gold charcoal recirculation, leaching slurry processing etc other seven operation stage.
Large scale gold ore dressing, the gold ore which associated more silver and copper.
After simplifying the leaching process, it has the advantages of saving infrastructure production costs; gold minerals have high dissolution rate and high recovery rate; adopts high-efficiency and low-cost rapid desorption electrolysis system, the system is high-temperature, high-pressure, non-cyanide, desorption automatic control, efficient, rapid, Low consumption characteristics.
1200TPD gold ore CIL customer case
This is our factory in Sudan project, The project adopts cyanide leaching gold extraction technology (CIL). The design scale is 60,000 tons per year, 200 tons per day, 300 working days per year.
This gold mine grade is 2-5g per ton, due to its low grade and complex surface mineral property, it is difficult to maintain a high recovery rate in normal operation. Our mechanical engineers comprehensive analysis finally determine to use: CIL cyanide leaching gold extraction process.
Raw materials through crushing, grinding processing, when the particle size of 200 mesh content reach to 90% - 95%, stir and cyanide the slurry, then leaching, activated carbon counter current adsorption, gold loaded carbon desorption electrolysis etc steps, the finished product is gold ingot.
2.Gold ore flotation process
According to the differences of physical and chemical properties of gold ore surface, gold ore flotation production line is treated by flotation reagents, the gold deposits are selectively stick to the bubbles for the purpose of separation.
Gold flotation process is divided into several parts, such as crushing, grinding and flotation etc.It will be used jaw crusher, ball mill, spiral classifier, flotation machine, the mixing tank, thickener and other equipment.
Vein gold ore; Sulfide gold ore.In addition to separate gold, the process can also be used for flotation of copper ore, lead and zinc ore, fluorite ore, feldspar ore, graphite ore, tungsten ore and other metals and non-metal ore.
The gold mine has high recovery rate and low drug consumption. The new flotation agent is used to quickly collect gold sulfide concentrates for efficient and comprehensive utilization.
600TPD Flotation Gold Ore Dressing Customer Case
In 2017, our factory and South African customers reached an engineering contract agreement for the gold ore beneficiation project. The gold ore beneficiation project has a designed capacity of 180,000 tons per year, 600 tons per day, and 300 working days per year. Although the mine's gold grade (5%-13%) is not low, the mineral composition is complicated and it has become one of the difficulties of this project. After comprehensive analysis, testing and experimentation, Jinhao Mine mechanical engineer determined the multi-stage grinding and flotation mixed beneficiation method, including: three-stage grinding, one roughing, two sweeping, and five selections. After processing, the original gold ore concentrate with a taste of 5%-13% was upgraded to a gold ore concentrate with a gold content of 90%. The main equipment of this project includes jaw crushers, ball mills, spiral classifiers, flotation machines, thickeners, mixing tanks and many other equipment.
3.Gravity Gold Processing Line
Gravity separation process is the use of mineral density and particle size differences, with the help of the dielectric fluid and all kinds of mechanical force combined to cause appropriate loose layer and separation conditions, in order to gain the technological process of different density and different particle size of products.
It is mainly used for the treatment of alluvial gold, as well as in combination with other types of mineral processing techniques.
In addition to deal with gold processing, it can also be used for processing tungsten ore, tin ore, manganese ore, titanium ore, tantalum niobium ore, barite, Iron pyrite, antimony, chrome ore, etc.
The set of process equipment is simple, low cost, with high efficiency, energy saving, environmental protection, economic and other advantages.
