Problems solved by technology

[0002] Collectors are the key factors affecting bauxite flotation desiliconization. The problems of collectors such as fatty acids and fatty acid derivatives in bauxite positive flotation desilication production mainly include: poor selectivity in the flotation process, flotation The foam is viscous and has poor adaptability to the ore properties, resulting in difficulty in the separation of aluminum minerals and silicon-containing minerals and a low recovery rate of concentrates; when the properties of ores change, especially when the mud content increases, the control of the flotation process is difficult, and even It is difficult to guarantee the quality of the concentrate; in addition, this type of collector has poor low temperature adaptability, and the amount of collectors under low temperature conditions increases greatly, and even cannot be used. Effective separation, which will lead to a substantial increase in beneficiation costs

Abstract

The invention relates to the technical field of fine chemical engineering, in particular to a beneficiation mixed collector. The beneficiation mixed collector is composed of, by weight, 60-80% of oleic acid, 15-20% of lauric acid, 5-10% of N, N-dimethylformamide-dimethyl sulfate, 5-10% of single carboxyl fatty acid, 5-10% of iso-20 ether and 8-12% of iso-octane. The beneficiation mixed collector is good in performance, saves energy and lowers consumption.
