Problems solved by technology

The composite coal preparation flotation agent uses traditional diesel oil as a collector. Due to the relatively strong hydrophilicity of weathered coal, the flotation effect of strongly hydrophobic diesel oil, kerosene, gasoline, etc. is poor

Abstract

The invention relates to a mixed-ether-based floatation agent and a preparation method thereof and belongs to the technical field of coal floatation agents. The mixed-ether-based floatation agent includes, by mass, 50-60 parts of a mixed ether, 40-50 parts of a foaming agent, and 0.1-0.2 part of a surfactant. The mixed-ether-based floatation agent can enhance hydrophobicity of weathered coal, so that weathered coal washing recovery rate is increased, washing quality is controlled, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of flotation agents, and in particular relates to a mixed ether-based flotation agent and a preparation method thereof. Background technique [0002] Flotation, also known as coal washing, is the process of sorting out clean coal that meets the quality requirements of users from raw coal. Coking coal has certain requirements for ash and sulfur content. Washed clean coal must be used. The lithofacies composition of coal As well as the quantity, type, nature and distribution of minerals in coal, they are all factors that affect the selectivity of coal. [0003] Flotation agents are generally added to coal during flotation. The existing flotation agents include collectors, foaming agents, emulsifiers and other trace additives. There are many kinds of collectors used in coal flotation, mainly non-polar hydrocarbon oils, including diesel, kerosene, gasoline, etc., and insoluble esters. In coal flotation, most f...
