Abstract

The invention discloses a mining frother for rare earth ore flotation and a preparation method thereof, and belongs to the technical field of ore flotation. The mining frother for rare earth ore flotation is prepared from, by weight, 40-50 parts of sodium fatty acid methyl ester sulfonate, 10-15 parts of sodium dodecyl sulfate, 10-15 parts of sodium alpha-olefin sulfonate, 10-15 parts of polyvinyl alcohol, 10-15 parts of alkyl polyglucoside, 10-15 parts of N-lauroyl glutamate diester, 10-15 parts of glycerol, 5-10 parts of sodium lauroyl sarcosine, 5-10 parts of sodium lauroyl hydrolyzed silk, 5-10 parts of aluminum potassium sulfate, 5-10 parts of guar gum, 2-5 parts of sodium alginate and 5-10 parts of froth stabilizer. The mining frother for rare earth ore flotation is high in frothing speed, strong in frothing power, high in froth stability and good in hard water resistance, ore obtained after flotation is high in grade, and the recovery rate is high.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a foaming agent for rare earth ore beneficiation and a preparation method thereof. Background technique [0002] Rare earths have the reputation of "industrial vitamins", and now they have become extremely important strategic resources. Rare earth elements have been widely used in petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the value of rare earth elements will increase. [0003] 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) group...
