Embodiment 1

[0023] The fluorite ore flotation collector of the present embodiment is prepared from the following raw materials in weight percentage: phenylaminophosphoric acid 50%, oleic acid 30%, sodium alkylsulfonate 15%, water glass 5%, according to the above Weigh the raw materials in percentage by weight, heat oleic acid to 60°C-70°C, add phenylaminophosphoric acid and stir, then add sodium alkylsulfonate and stir, finally add water glass and stir for 1 hour, and stir evenly to obtain Fluorite ore flotation collector.

[0024] Using the prepared fluorite ore flotation collector, the flotation grade is 42.73% of the raw ore, the obtained titanium concentrate grade is 92.56%, and the recovery rate is a good indicator of 87.23%.

Embodiment 2

[0026] The fluorite ore flotation collector of the present embodiment is prepared from the following raw materials in weight percentage: phenylaminophosphoric acid 51%, oleic acid 29%, sodium alkylsulfonate 15%, water glass 5%, according to the above Weigh the raw materials in percentage by weight, heat oleic acid to 60°C-70°C, add phenylaminophosphoric acid and stir, then add sodium alkylsulfonate and stir, finally add water glass and stir for 1 hour, and stir evenly to obtain Fluorite ore flotation collector.

[0027] Using the prepared fluorite ore flotation collector, the flotation grade is 42.73% of the raw ore, the obtained titanium concentrate grade is 92.17%, and the recovery rate is a good indicator of 87.02%.

Embodiment 3

[0029] The fluorite ore flotation collector of the present embodiment is prepared from the following raw materials in weight percentage: phenylaminophosphoric acid 52%, oleic acid 28%, sodium alkylsulfonate 15%, water glass 5%, according to the above Weigh the raw materials in percentage by weight, heat oleic acid to 60°C-70°C, add phenylaminophosphoric acid and stir, then add sodium alkylsulfonate and stir, finally add water glass and stir for 1 hour, and stir evenly to obtain Fluorite ore flotation collector.

[0030] Using the prepared fluorite ore flotation collector, the flotation grade is 42.73% of the raw ore, the obtained titanium concentrate grade is 92.09%, and the recovery rate is a good indicator of 86.57%.

Abstract

The invention discloses a flotation collecting agent, particularly relates to a fluorite ore flotation collecting agent and a preparation method thereof, and belongs to the technical field of mineralflotation collecting. The fluorite ore flotation collecting agent is prepared from phenylamino phosphonic acid, oleic acid, alkyl sodium sulfonate and water glass. The fluorite ore flotation collecting agent is prepared through the following steps: heating sodium oleate, adding the phenylamino phosphoric acid, stirring, adding the alkyl sodium sulfonate, stirring, adding the water glass and fullystirring to obtain the fluorite ore flotation collecting agent. The fluorite ore flotation collecting agent is low in cost, safe and environmentally friendly, and the quality grade of fluorite ore canbe effectively improved after the components cooperate with one another.

Description

technical field [0001] The invention relates to a flotation collector, in particular to a fluorite ore flotation collector and a preparation method thereof, and belongs to the technical field of mineral flotation collectors. Background technique [0002] Fluorite ore is also known as fluorspar. Its main chemical composition is calcium fluoride, which usually exists in the form of single mineral, fluorite-calcite, fluorite-barite and other symbiotic and associated forms. The relationship is complicated, the encapsulation phenomenon is serious, and the physical and chemical properties of fluorite and gangue mineral surfaces are similar, making it difficult to effectively separate them. The processing requires high grade concentrates, so multiple flotations are required to improve the quality of the products. , flotation is the main method of fluorite ore beneficiation. The development of high-efficiency flotation agents is the key to improving the re-selection index. Usually, ...
