摘要
将净煤(密度小于1.35 g/m3)与石英、高岭土、黄铁矿、方解石分别按照一定比例混合,将混合物通过摩擦电选的方法进行分离,通过对分离后样品的取样、产率、灰分、硫分分析,研究了煤中矿物质在摩擦电选过程中的脱除规律。
Mix the pure coal (with the density of less than 1.35g/m^3) separately with quartz, kaolin, iron pyrite, calcit in certain proportion, then separate the mixture with friction electricity. After separating, through the analysis of sample - taking, production rate, ash content, sulphur content, research the shedding law of the minerals existed in coal in the procedure of friction electricity.
