Clay processing method, basically have hand picking, re-election, the flotation methods. One of them, to look at flotation of concentrator for further, followed by hand picking, use heavy optional choose factory is less. A few clay flotation process through the use of single concentrator, most clay concentrator adopt combination process, like the hand picking – flotation process, hand picking – re-election – flotation process.

Crushing and Grinding stage

The extracted 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 conveyor and feeder, and is milled by ball mill.

Classifying stage

The subtle milled 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 can be classified by screw classifier.

Mixing and Flotation stage

The classified 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 flotation 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.

Concentrator thickening and drying

Then clay is separated from others. Since the separated are wet, they should be dewatered by thicker initially, and dried by dryer.
