Problems solved by technology

[0015] The technical problem to be solved by the present invention is that there is no high-efficiency selective phosphorus mineral collector with a wide range of applications for flotation of phosphate rock, and the collectors of conventional phosphate rock flotation have relatively large defects, especially When the flotation effect of low-grade phosphate rock is not ideal, it provides a kind of phosphate rock flotation collection with good selectivity, little interference from other ions in the pulp, strong collection performance and certain foaming performance.

Abstract

The invention discloses a phosphate rock flotation collector. The phosphate rock flotation collector comprises, by weight ratio, 20-70 parts of Y and 30-80 parts of S; the Y comprises, by weight ratio, 60-30 parts of lauryl amine, 20-40 parts of mixed amine and 20-30 parts of hydrochloric acid; the S comprises, by weight ratio, 20-40 parts of oleic acid, 20-40 parts of phenmethyl hydroximic acid, 20-30 parts of caustic soda and 10-20 parts of sulfuric acid. The invention further discloses a preparation method of the phosphate rock flotation collector. The phosphate rock flotation collector and the preparation method have the beneficial effects that the selectivity and the collecting property are strong, the flotation time is short, the interference caused by other ions in pulp is small, the technological operation is simple, and the economic benefit is remarkable; the grade of P2O5 can be improved by about 5%, and the phosphorus comprehensive recovery rate can be improved by about 10%; poisonous and side effects do not exist, pollution to the environment can be avoided; and the raw material source channels are convenient, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of beneficiation reagents for mineral processing engineering, in particular to a phosphate rock flotation collector and a preparation method thereof. Background technique [0002] At present, there are relatively few types of collectors for phosphate rocks. At present, flotation collectors for phosphate rocks are mainly divided into: fatty acid collectors, fatty acid mixed collectors, cationic amine collectors, and ether amine collectors. Collectors, amphoteric collectors, code-named collectors, etc. [0003] (1) Fatty acids are widely used in the flotation of phosphate rock as a class of very classic flotation collectors. Due to its wide source and low price, it is favored. For example, fatty acids such as oxidized paraffin soap and tall oil and their soap collectors play an important role in the flotation of phosphate rock at home and abroad. [0004] (2) Fatty acid mixed collectors. During the use of fa...
