Abstract

The invention discloses a coal slime flotation reagent. The coal slime flotation reagent comprises, by weight, 30-40 parts of cycloalkanes, 15-30 parts of octanol, 15-30 parts of diesel oil, 3-5 partsof coconut oil, 0.5-1.5 parts of catalysts and 0.5-1 part of regulators. All the components are mixed and uniformly stirred at the normal temperature. The coal slime flotation reagent is free of toxicity and pungent smells, less in dosage, high in safety, energy-saving and efficient, the coal dressing cost is saved, and the clean coal yield is improved.

Description

technical field [0001] The invention relates to a coal slime flotation agent, which belongs to the technical field of coal separation. Background technique [0002] Coal slime flotation is a kind of coal that uses the difference in physical and chemical properties of the surface of coal and gangue, and can expand the difference in wettability between coal and gangue by adding specific flotation agents, so as to realize the separation of coal and gangue. Mud Sorting Technology. The reason why flotation can be widely used in coal slime separation is that it can flexibly control the flotation process through flotation agents, and effectively realize the separation of coal and gangue according to people's requirements, so that coal resources can be comprehensively and efficiently use. [0003] Flotation agents can improve the properties of gas, liquid, and gas in the flotation system, so that the size, quantity, life, and floating speed of the generated bubbles can meet the fl...
