process of washing coal in dense medium cyclone plant

A typical dense medium type coal preparation plant included dense medium vessel circuitry for the “coarse” raw coal dense medium cyclone circuitry for the “intermediate” size fraction with a spiral or wateronly cyclone circuit for raw coal down to about 015 mm Ultrafines 015 mm x 0 were either discarded to refuse or processed in froth flotation circuits
