There is slight gold in the mineral ore. In order to extract gold, it is necessary to crush and grind the gold ore and then beneficiation method is used to preconcentrate or separate gold from the ore.  Gravity separation and flotation are mostly used in gold beneficiation. Gravity separation plays a very important role in producing gulch-gold. Flotation is a mineral processing method which is widely used in rock gold mines.

Abstract:

Gravity separation method is an earlier mineral processing method. According to the different density between minerals, the different gravity, fluid power or mechanical force in the moving medium, this method achieves the process of separating mineral particles in the light of density. Gravity separation method still plays an important role in the contemporary mineral processing method.

Due to the different size composition of gulch-gold in gold mine, different beneficiation equipments have different particle size limit on effectively processing materials. Therefore, the reasonable gulch-gold separation process should combine several different gravity separation equipments. Gravity separation is an effective and economical method to process gold ore.

Technic Requirements:

In the gravity separation process, we can use the gravity separation equipments such as Jigging Machine, Shaking Table, Spiral Chute etc. Jigging Machine is good at the separation of coarse mineral. Under the condition of high deviation and separation of mineral monomer, it is very suitable for gulch-gold selection, which is easy to operate and has a large processing capacity. Shaking Table does well in fine mineral separation. According to the different particle sizes of the ore which needs separation, shaking tables which separate 0.5-2mm are called Coarse Sand Bed and tables which separate 0.074-0.5mm are called Fine Sand Bed and tables which separate 0.037-0.074mm are called Slurry Bed.  Spiral Chute is suitable to process fine gold ore with slight mud and separate ore particles between 0.03-0.6mm. The comprehensive cost of Spiral Chute is relatively low.

Technic Process :

The raw ore is crushed by the crusher and then remove iron. After screening in the Vibrating Screen , qualified materials will go into the Ball Mill for grinding. After grinding, the raw ore goes into the Jigging Mahicne, Centrifugal Gold Separator, Shaking Table, Spiral Chute for gravity separation, and finally get gold concentration.

 

Production Advantages:

①simple process, hard to appear problems while production, easy and quick training for worker
②less need of machines, low investment cost, large processing capacity, short payback period
③green and environment-friendly technic process ,directly dischargeable tailings, huge cut in the investment of the whole plant selection project
④stable and efficient production line, high recovery rate.
