Coal beneficiation: theory and practice
Dry coal beneficiation processes were widely applied in Europe and the United States during 1930–65. However, they were later abandoned largely because the separation was not accurate, the available technology severely restricted feed size and throughput, and moisture presented a major inhibiting factor on performance.
