A device for flotation of coal slime using coal gangue

Technical Field

The utility model relates to the technical field of coal slime processing, in particular to a device for flotation of coal slime using coal gangue.

Background Art

Gangue refers to solid waste or by-products generated during coal mining or coal processing. It is mainly composed of impurities and rocks that are not separated by flotation or other treatment methods in coal. The composition of gangue usually includes rocks, soil, minerals and some unburned coal, which poses problems for the environment and resource utilization. The flotation coal slime device can effectively extract coal particles from the gangue through physical and chemical separation technology. It can be turned into valuable products and increase economic benefits. The extracted coal particles can be used as fuel or for other industrial purposes.
