Liquid-solid compound collecting agent for coal slime flotation and preparation method thereof

Abstract

The invention discloses a liquid-solid compound collecting agent for coal slime flotation and a preparation method thereof. The liquid-solid compound collecting agent is prepared by mixing high-floatability ultrafine coal-based particles with a liquid collecting agent in proportion, wherein the mass percentage of the ultrafine coal-based particles is 0.5-5%, and the mass percentage of the liquid collecting agent is 90-99.5%. The high-floatability ultrafine coal-based particles in the liquid-solid compound collecting agent can be adsorbed on the surfaces of floated coal particles in the flotation process, the surface hydrophobicity of the floated coal particles is improved, the efficiency of adhesion between the coal particles and bubbles can be improved, and the coal slime flotation effectis effectively improved. The liquid-solid compound collecting agent is low in cost, good in effect and capable of well improving the coal slime flotation efficiency and improving the recovery rate ofa clean coal product.

Description

technical field [0001] The invention belongs to the technical field of flotation reagents, in particular to a liquid-solid composite collector for coal slime flotation and a preparation method thereof. Background technique [0002] As my country's basic energy, coal occupies an important position. As far as the current situation is concerned, the development of the national economy and the progress of industry are inseparable from basic energy. Coal has made a significant contribution to China's socialist construction, but in the processing and use of coal, most of the coal resources have insufficient utilization, low conversion efficiency, and serious waste of resources. In order to solve these problems, further research on coal is currently underway. Processing, improving the utilization efficiency of coal, and producing high-quality coal resources; ultra-pure coal is a new type of high value-added coal resource, which can prepare activated carbon, oil-water coal slurry an...
