Abstract

The invention discloses a foaming agent for mineral flotation and a preparation method thereof, and belongs to the technical field of mineral flotation. The foaming agent for mineral flotation is prepared from, by weight, 50-60 parts of methyl ester sulfonate, 25-30 parts of lauryl sodium sulfate, 20-30 parts of sodium alpha-olefin sulfonate, 10-15 parts of polyvinyl alcohol, 10-15 parts of glyceryl monostearate, 10-15 parts of polyvinyl pyrrolidone, 10-15 parts of N-lauroyl glutamic acid diester, 5-10 parts of potassium lauroyl sarcosinate, 5-10 parts of sodium lauroyl hydrolyzed silk, 5-10 parts of lauryl diethanolamide, 5-10 parts of guar gum, 5-10 parts of sodium alga acid and 5-10 parts of a foam stabilizer. The foaming agent is high in foaming agent, high in foamability, high in foaming stability and good in hard water resistance.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a foaming agent for mineral flotation and a preparation method thereof. Background technique [0002] Frothing agent is one of the main reagents for ore flotation. The research shows that the performance of the foaming agent has a significant impact on the flotation index. Foaming agents are generally heteropolar surface-active substances, and their molecular structure is composed of non-polar lipophilic (hydrophobic) groups and polar hydrophilic (oleophobic) groups, forming both hydrophilic and So-called "amphiphile" molecules of the lipophilic type. The lipophilic group can be aliphatic hydrocarbon group, alicyclic hydrocarbon group and aromatic hydrocarbon group or aliphatic hydrocarbon group, alicyclic hydrocarbon group and aromatic hydrocarbon group with O, N and other atoms; the hydrophilic group is generally carboxylic acid group, hydrocarbon group, sulfonic ac...
