Problems solved by technology

However, due to the poor selectivity of anion (fatty acid) collectors, resistance to hard water, high temperature requirements, large dosage of chemicals, high production costs, or odor, relatively complicated production processes and other shortcomings, while cationic (amine) collectors Collector, good selectivity, low reagent consumption, but sensitive to mud, sticky foam, difficult to defoam, difficult to realize flotation foam transport, cationic collector is rarely used in actual production

Abstract

The invention discloses a froth flotation cation collecting agent and a preparation method thereof, and belongs to the technical field of ore dressing. The froth flotation cation collecting agent consists of the following raw materials in percentage by weight: 15-30% of C12-C18 fatty acids, 5-15% of N-chlorosuccinimide, 20-50% of ether amine, 5-20% of industrial fusel, 2-10% of emulsifier, 1-8% of diesel oil and the balanced water. The sum of the raw materials is 100% in percentage by weight. The preparation method comprises the following steps of performing chlorination on the C12-C18 fatty acids and the N-chlorosuccinimide; adding the industrial fusel, the emulsifier and the diesel oil in the mixture of the C12-C18 fatty acids and the N-chlorosuccinimide; and stirring the mixture uniformly and adding water in the mixture to obtain the froth flotation cation collecting agent. Compared with the conventional collecting agent, the froth flotation cation collecting agent is high in selectivity, high in argillization resistance and stable in performance and is low-temprature-resistant; foams are not tacky and dissipate easily; normal-temperature flotation can be realized; chemical consumption is reduced; and R2O3 in concentrates is greatly reduced.

Description

technical field [0001] The invention relates to a cationic collector for phosphate rock flotation and a preparation method thereof, belonging to the technical field of mineral processing. Background technique [0002] Yunnan is an area rich in phosphate rock resources. One of the main uses of phosphate rock is the production of phosphoric acid and high-concentration phosphate fertilizer. However, there are few rich phosphate rocks in Yunnan, and most of them are low- and medium-grade collophosite. Especially with the increasing demand for downstream phosphorus chemical industry, phosphate rocks are continuously mined, rich ores are getting less and less, and the grade of raw phosphate rocks continues to decline. The mined phosphate rock must be beneficiated and enriched in order to meet the raw material quality requirements of the high-concentration phosphoric acid and phosphate fertilizer industries. [0003] Now, phosphate rock flotation mostly adopts the flotation proces...
