concern. Brown coal is a type of the common low-rank coal which shows the special physical property of an easy degradation in water. Thus it is unfavorable to separate brown coal by wet processing technology as well. Therefore it is significantly important to develop a dry coal beneficiation technology in current energy utilization field.
