Abstract
The invention discloses a coking middling coal coarse grinding and floatation method and belongs to the field of a coal washing and dressing technology. Firstly, granularity of heavy medium middling coal in a coal preparation plant is reduced below 3mm through crushing; then, wet ore grinding is carried out by a ball mill, and granularity of the material is less than 0.5mm after ore grinding; and finally, recovery is conducted by a floatation method. The method provided by the invention is mainly characterized by coarse ore grinding and drug-free floatation. The method has advantages of low energy consumption, simple operation and low investment and operation costs.
