Study on Preparation of Super Clean Coal with Selective Flocculation-Flotation Technology on Taixi Anthracite

Article Preview

Abstract:

Based on the coal petrology character of Taixi anthracite, the selective flocculation-flotation preparation of super clean coal is studied. The influences factors of the type and dosage of dispersant, the type and dosage of flocculant, pulp density etc etc on its effect is analyzed, and, through the orthogonal experimental methods, the salience order, interaction, and the optimum combination of the main factors is revealed. The finally test results indicate that we can obtain an ash about 1.29% at a yield of 41.85%％ super clean coal, thus will provide basis for the future super clean coal industrialization.
