Coal Beneficiation an overview ScienceDirect Topics
Coal preparation, or beneficiation, is a series of operations that remove mineral matter ( ie , 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 controlIn India, coal has to play the anchor role in this transition The rise in the prices of coking coal is expected to affect the prices of steel and iron ore, which would also be a hindrance in transitioning to green methods Higherpriced coking coal increases the cost of producing steel via blast furnaces, both in absolute terms and relative toSteel Coal and Iron ore report
