Studies on Regulator Experiment of a High-to-float High-ash Fine Coal

摘要：

Aim at high-to-float high-ash fine coal with large content of granules, in order to reduce pollution of carried fine slime to quality of concentrate coal, soluble glass, sodium hexametaphosphate and cornstarch these three kinds of regulators were choosen to carry out flotation reducing ash experiment. Result showed that, cause of poor selectivity of fine coal is mainly small quality, big surface area and the poor dispersion of fine coal. When sodium hexametaphosphate dosage is 1500g/t, the kerosene dosage is 370g/t, the foam beater GF dosage is 150g/t, production rate of concentrate coal is 57.69％, and ash content of concentrate coal is 12.04％. Under the same condition, separation index of sodium hexametaphosphate as regulator is superior to cornstarch and soluble glass.
