Dry Beneficiation Of Fine Coal Using Planar Air Jets

Beneficiation of fine coal (+500 m –2000 m) is a worldwide problem in the mining industry, especially dry beneficiation of fine coal. Coal beneficiation can be divided primarily into two methods, namely wet- and dry beneficiation. Wet beneficiation methods are utilized in.Systems. Dewatering and drying of fine coal slurries can be expensive. The potential means to avoid the expense of dewatering fine coal products is to use dry beneficiation processes. Dry beneficiation is used for a wide variety of bulk materials, but has not gained wide popularity in the coal.
