A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes.

Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

A cyclone is a device that uses centrifugal forces to classify solid particles, in a liquid stream, by size and/or density. What does a Cyclone do? If a cyclone is fed with a sand and water mixture containing a range of particle sizes, most of the fine sand will report to the overflow (the top of the cyclone), together with most of the water.

a mere 15%, the profit generated by a single 1000mm cyclone under these conditions is enough to pay for that cyclone in just more than a single shift's time (R300,000 ÷ (R132.22 ÷ 2 x 15%) = 8hrs 25min). Generating a profit in the order of R10/sec it becomes clear why it is worthwhile to ensure the cyclone is operating optimally.

"Unlike with a cyclone or sand screw, this machine is not trying to lift the fines out," Bennington says. "We're literally pushing them through the dewatering screen with a high-pressure, low-volume spray bar that pushes the dirty water through the bottom. With this process, you can reduce the silt by at least 4:1."

Dense medium cyclones (DMCs) are used as the main coal benefication process in modern coal washing plants because of their high capacity and efficiency (Chu et al., 2009). The relative density of the dense medium used to enhance the separation is the key factor that affects the quality of coal after this DMC circuit.
