COALY MATTER FLOTATION METHOD

摘要

FIELD: mining engineering; processes.;SUBSTANCE: method of coaly matter flotation from gold ore involves a preliminary wet grinding and a subsequent flotation introducing potassium butyl xanthate and a foaming agent T-80. Sodium lauryl sulfate ethoxylate in the ratio of 5:1 is added as an activating agent of the hydrophobisation of the coal particle surface after which a foaming agent T-80 is fed.;EFFECT: enhanced flotation efficiency.;1 tbl
