摘　　要：通过试验分析了宝日希勒褐煤及其半焦的可选性,结果表明:宝日希勒褐煤及其半焦是可选的,采用褐煤制备半焦,再对半焦进行分选,可获得多种半焦产品;并且,褐煤在制备半焦的过程中易发生碎裂,使得半焦的粒度上限小于褐煤的粒度上限,有利于半焦的洗选加工。The article analyzed the washability of Baorixile＇s lignite and semi- coke through experiment. The result shows that the lignite and semi - coke can be separated in theory. The semi - coke prepared from lignite, and then separation the semi - coke can get a variety of semi - coke product. Besides, due to the lignite broken during the preparation of semi -coke, so the upper limit of particle size （13 mm） of semi -coke is less than that of the lignite＇s （50 mm） , which can be beneficial to separate semi- coke
