Process Introduction:
The flotation method is the most widely used ore dressing method in the production of gold. It has high flotation efficiency and can handle fine-grain-dipped ore. For ore with complex composition, the flotation method can get good separation results. Flotation method is often used to treat gold ore containing sulfide minerals with high floatability. The sulfide ore mainly includes sulfide-depleted gold ore (mostly quartz vein type or hydrothermal alteration type), poly sulfide gold ore and polymetallic. auriferous sulfide ore, the flotation process can maximize the enrichment of gold into the sulfide mineral, and lower the beneficiation cost.
Gold ore is a mineral aggregate with sufficient gold content and can be used industrially. Gold mines are places where gold is obtained through mining operations According to the structural state and the content of gold in the ore, the gold deposit is a kind of industrial deposit which is formed by Mineralization The gold minerals in gold deposits can be divided into three categories: gold minerals, gold-bearing Minerals, and gold-bearing minerals. The so-called independent mineral of gold refers to the gold in the form of gold minerals and gold-bearing minerals.
1. Crushing System
The rock gold is fed to the rough jaw crusher by a trough feeder to crush. And then delivered to the fine jaw crusher for second crushing.
2. Grinding System
After the crushing, the gold ore sends to the ball mill to grind. The output material of the ball mill(<1mm) goes to the spiral classifier for grading. The 200-mesh slurry can go to the next flotation system and the larger ones return to the ball mill.
3. Flotation System
The 200-mesh slurry will be firstly sent to the mixing tank by slurry pump, to make sure material is mixed completely, then from mixing tank go to flotation machines, need to add different chemicals in flotation machine to separate out different minerals, the flotation process has the primary selection, secondary selection, and final selection, this is for increase minerals grade to maximum after the process. If need a higher grade, then need to flotation more times. Will get each mineral concentrate ore after the flotation system.
4. Concentrate Ore Filtering System
After getting the minerals to concentrate ore from the flotation system, use the thickener to concentrate, make higher density, then send to disc vacuum filter machine to filter water, and get more dry concentrate minerals. Then can dry in the sun or by drying machine to get complete dry minerals to concentrate ore.
