Abstract
The establishment of large scale thermal coal preparation plants provides society with high-quality environmentally friendly coal product. It also allows China to reliably and efficiently utilize coal resources. The situation and characteristics of thermal coal resources in China were briefly introduced. Major issues existing in the processing of thermal coal, Due to the characteristics of thermal coals such as non-caking coal, long flame coal and lignite, it is necessary to explore and optimize the beneficiation of thermal coal to overcome disadvantages arising from the preparation of all size fractions. The authors believe that optimization surrounding pre-washing screening could provide a new idea and beneficial reference to the selection of flowsheet for the preparation of thermal coal. typically lignite and non-caking coal, were extensively analyzed. The optimization of the ratio of process investment was proposed. A screening classification was recommended prior to the primary preparation of thermal coal. The feasibility of this optimization was investigated. It is concluded that such optimization provides an excellent reference to the selection of beneficiation flowsheet for thermal coals.
