Concentration Process for Gold Ore Selecting:
1. Crushing and grinding stage
The extracted ore should be crushed by jaw crusher initially and then by fine crusher. When it gets the reasonable fineness, it is transported into ball mill by elevating conveyer and feeder, and is milled by ball mill.
2. Classifying stage
The subtle milled ore gets the next procedure: classification. There is a theory that if the weights of solid particles are different, the sedimentations will be different, and the mixed ore can be classified by screw classifier.
3. Mixing and Floatation stage
The classified ore gets into mixing tank for fully mixing. At this stage, chemical agent for foam can be added. After fully mixing, the slurry will enter into flotation machine.
When the floatation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.
4. Concentrator thickening and drying
Then copper concentrate is separated from others. Since the separated ore are wet, they should be dewatered by thicker initially, and dried by dryer.
Our XKJ Series Advantages of Beneficiation Line:

2. Technical is mature.
3. We have our own R&D department.
4. Many successful case is for reference to give later client better service.
Features of XKJ series new technology ball mill:
1. Ball mill is as main grinding equipment before separation stage is absolute key product in our company; we manufacture many ball mills every year.
2. We have our own R&D department and can make the update ball mill by ourselves.
3. Many successful users’ work site at home and abroad.
The spiral classifier:
It is widely applicable to ore dressing industry and building materials. During grinding process, ball grinding mill with spiral classifier forms a circuit. In this circuit, spiral classifier plays a role of separating qualification ore grain and disqualification ore grain.
The agitation tank:
It is necessary equipment of mining machine. Though this agitation tank it can mix the slurry and the medicine efficiently. It is suitable for slurry with density of no more than 30 %( by weight).And the size of the fixed component of the slurry particle less than 1 mm. It has a cylindrical radial circulation mechanical blending form with the spiral impeller and flat bottom. Then the mixed slurry will flow into the flotation machine.
The flotation machine:
Flotation machine is widely used in copper, lead, zinc, molybdenum, gold and other non-ferrous metals, ferrous metals and non-metallic minerals, roughing, selective and potent anti-flotation operation.
Through V- belt transmission, which brings centrifugal effect to form the negative pressure. On the one hand, the flotation machine inhales sufficient air to mix with ore slurry; on the other hand it stirs ore slurry and mix with medication to form the mineralized froth. By adjusting the height of flashboard to control the liquid level and make the useful froth scraped by loam board.
