This is due largely to the increasing costs of magnetite. A wet drum magnetic separator that was once viewed as a necessary on-going expense may now be viewed as an avenue to significant cost savings to the operation. This has recently led to increased activity with coal wash plants upgrading the magnetite recovery circuit.

Implementation of the above recommendations reduced the magnetite losses in the coal washing plants from about 1.64 kg/t to 1.3 kg/t. This in terms of raw coal processed in the cyclone circuit reduced the magnetite consumption by 639 t, resulting in a savings of US$27,500/annum. The cost savings are shown in Table 5.
