摘要：
A strong incentive exists for the coal-preparation engineer to improve plant efficiency by modifying circuits and upgrading process equipment, since these result in lower production costs and more valuable plant products. At the Grootegeluk Coal Mine, it was found that the overall plant efficiency could be improved by modifications to the dense-medium circuits, the installation of additional process equipment for the recovery of fine coal, and improvement of the fine-material processing circuit. Apart from these modifications, there is still potential to increase the plant efficiency, particularly in the utilization of plant waste, the recovery of slimes, and even the improvement of cycloning performance as a result of new cyclone design. This paper points to the potential wealth locked up in existing coal-preparation plants, and shows how the coal-preparation engineer, with new technology at his disposal, can unlock this wealth.
