Introduction: Coal Washing is a process of enrichment of combustibles in coal by removal of noncombustible impurities utilizing industrial separators mainly based on difference in Specific Gravity of Coal and associated impurities like Shale, Sand Stones etc. so that we get marketable coal suitable for the target consumers. The Washed Coking Coal is meant for Steel Plants.

Among them, coal slime water is the industrial tailings water of the wet coal washing process in coal mines. According to incomplete statistics, the wastewater generated by coal washing processing plants exceeds ×107t every year. The amount of water used for coal washing is huge and the slime water generated after coal washing contains various pollutants.

Dense Media Separation. A heavy medium is a heavyfluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

Coal Washing Exploration in India dates back to 1900s; though, first coking coal washeries in India were installed after independence. At present, most of the coking coal washeries are owned by Public Sector Companies; whereas, most of the noncoking coal washeries are owned by Private Sector. Even after six decades of coal washing practices, there has not been significant development in the ...

Abstract. Most coal requires some preparation before use. Preparation may range from simply crushing to provide a size consist suitable for certain types of boilers to extensive size reduction and cleaning to remove sulfur and ashforming mineral matter. At present, coal cleaning is accomplished through physical separation of particles low in ...

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