Influence research flocculation reagents on indicators flotation of a coal trifle and development the reagent mode

Abstract


Enrichment of a coal trifle is the actual task facing the coal preparation works. With change of ordinary coal its importance grows. The amount of slimes considerably increased in coals arriving on enrichment and the amount of the oxidized coals increased. All this negatively influences efficiency of process of enrichment of slimes and leads to increase in its cost. The solu-tion of this problem is connected with the correct selection of the most effective flocculation and floatation reagents which provide high overall performance of all factory in the conditions of rigidly closed water and slurry scheme. In this work experimental data on research of process of flotation of coal slime with use of vari-ous reagents collectors after a preliminary flocculation, with ap-plication floatation reagents the “Magnafloc” type are presented.
