WhatsApp: +86 18203695377Abstract. Coal is a physical mixture of high carbon value coal and rejects. Coal beneficiation is nothing but the separation of these high carbon value coal from rejects (noncarbonaceous material) in a coal body. Although the theoretical knowledge of coal beneficiation is available aplenty in coal preparation books; it is essential that mineral ...
