Run-of-mine (ROM) coal typically goes on a conveyor belt to a coal preparation plant. The coal preparation plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.

A Coal preparation plant generally uses gravity process equipment to separate the refuse from the product (coal). Heavy Media , jjg plants, spirals are the most common method used for coarse coal. Heavy media cyclones are being used for fines size fractions (100 mesh coal feed). Flotation is used to clean the -28 mesh size fraction, spirals are used for middling sizes ( 10 mesh to 60 mesh).

At coal preparation plant, Run-of-mine (ROM) coal is reclaimed using vibratory feeders, then loaded to crushing and screening plant by belt conveyor with heavy media cyclones processing (for coarse coal sizes - 2" x 10 mesh), spirals for the middling sizes (10 mesh x 60 mesh), flotation for the -60 mesh fine coal feed.

Process of Coal preparation plant

All feed coal (ROM) is crushed to -1.5" (or - 35 millimeters) before entering the plant circuits. The 2" x 10 mesh coal is screened and goes to the primary dense medium cyclone circuit. Oversize material is conveyed to coarse reject disposal facility. After crushing process, the coal is conveyed to raw coal silo. Raw coal is recovered from the silo by four vibratory feeders onto the coal processing plant feed conveyor, which is equipped with a tramp iron magnet and a belt scale, and conveyed to the des section of the processing plant.

The middlings (-10 mesh x 60 mesh) are processed in the Secondary Dense Medium Cyclone Circuit to recover the coal here, this produces a higher ash coal and is used as steam coal. The -10 mesh coal is deslimed at 100 mesh and then sized at 10 mesh x 100 mesh is processed in the spiral circuit to produce coking coal.
