The beneficiation of carbonate rich coal seam water CORE

Coal seams are commonly associated with poor quality water that requires treatment. Water treatment can be very expensive and can severely affect the profitability of mining projects. This study investigated the potential cultivation of Arthrospira maxima (Spirulina) in coal seam water to beneficiate coal seam water in order to effectively offset the water treatment cost.

coal handling beneficiation

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

COAL MINING AND THE ENVIRONMENT

Underground mining takes place when the coal seams are too deep to be able to afford to remove the overburden. Typically this occurs when the coal seam is >40m deep. The average depth of underground mining in South Africa is only 80m, which is shallow compared to many coalmines around the world. The deposit is mined by extracting square
