Coal Mining and Preparation Mineral Industry Solutions

The majority of coal preparation processes require large quantities of water. Exceptions to this include crushing, screening, and transportation. Coal is separated from inert materials using flotation. This yields wastewater rich in coal fines. This water must be treated for solids removal before it can be reused in the plant or discharged.

Appendix E: Coal Mining and Processing Methods Coal

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
