coal washing plant tailings

Coal Tailings

Coal Tailings, a Tata Steel by-product of coal, are generated from the finest circuit of the coal washing or coal beneficiation process. Primarily used as coal for Brick Kilns, Coal Tailings promise consistent quality with high calorific value. Tata Steel is well known among the chief non coking coal suppliers in India.
