Abstract

FIELD: mineral concentration; applicable in coal floatation at coal preparation plants. SUBSTANCE: method of coal floatation includes preliminary pulping of initial material, pulp conditioning with collector - heavy hydrocarbons and frothing agent, separation of combustible mass from the pulp into concentrate. In so doing, heavy hydrocarbons prior to introduction for conditioning are mixed with light catalytic gas oil with their ratio of 60:(40-75):25. EFFECT: increased concentrate yield by 1.4-2.4% and increased recovery of combustible mass into concentrate by 0.6-1.7%. 1 tbl

Изобретение относится к обогащению полезных ископаемых и может быть использовано при флотации угля на углеобогатительных фабриках. Способ флотации угля включает предварительное пульпирование исходного сырья, кондиционирование пульпы с собирателем - тяжелыми углеводородами и вспенивателем, разделение пульпы с выделением горючей массы в концентрат. Причем тяжелые углеводороды перед введением в кондиционирование предварительно смешивают с легким каталитическим газойлем при их соотношении 60:40 - 75:25. Это позволяет повысить выход концентра та на 1-4 2.4%,а также повысить на 0,6 - 1,7% извлечение горючей массы в конценрат.The invention relates to the enrichment of minerals and can be used for flotation of coal in coal processing plants. The method of coal flotation includes preliminary pulping of the feedstock, conditioning of the pulp with a collector - heavy hydrocarbons and blowing agent, separation of the pulp with the release of combustible mass into concentrate. Moreover, heavy hydrocarbons are pre-mixed with light catalytic gas oil before being introduced into conditioning at a ratio of 60:40 - 75:25. This allows one to increase the yield of concentrate by 1–4 2.4%, and also increase by 0.6–1.7% the extraction of combustible mass into a concentrate.
