Based on the analysis of current status of cleaning processes and equipment of pyrite reduction for high-sulphur difficult-to-wash coal ,that general view was given in this paper for following aspects. The new process for cleaning high-sulphur difficult-to-wash coal by three-proudest dense medium cyclone (including fine coal dense medium cyclone) with single low medium density performing two stage separation and monitored and controlled automatically; its commercial production results is reached in Nantong coal preparation plant ,Nantong coal Mining administration. And its prospects of extended application in china's high- sulfur coal mining areas and modification of coal washers cleaning difficult-to wash coal is also discussed.
