Abstract The producing reason of fine minerals and the impact on the production and transportation links were introduced briefly in this paper. Taking coal as an example, influence of the fine-grained mineral to coal quality was recommended, which showed that it was surely necessary to dehydrate the fine minerals. Several commonly used methods of fine mineral dehydration technology together with its concrete classification and working principle were expounded, including mechanical dewatering technology, drying technology, dehydration agent and compound filter dewatering technology. Application effect of these techniques in the dewatering of fine minerals was illustrated. According to current dehydration techniques, the main research and development direction of fine mineral dehydration technology was also prospected, which provided reference to research of dewatering of fine minerals.
