  Sada Coal - Coal Processing Plants

  Coal preparation plants usually use a number of processes taking advantage of the difference in density between coal and the mineral matter to separate the two (e.g. dense medium baths, froth flotation, cyclones). Other processes involved in the preparation plant include stockpiling and recovery, dewatering, disposal of waste ( "coal wash") and ...
