Study of the stability of the emulsion of ultramicroheterogeneous flotation reagents obtained by the method of ultrasonic dispersion

Abstract

The results of studies of the stability of the microemulsion of an ultramicroheterogeneous flotation reagent obtained from a mixture of oil from the Zhanazhol field and butyl xanthate (BX) in the following ratios are presented: oil: BX = 1: 1; oil: BX = 2: 1; oil: BX = 4: 1. It was found that the microemulsion has the greatest stability when the ratio of oil: BX = 4: 1, which was 99.3% after 120 hours of exposure. The supposed emulsifying effect of butyl xanthate in symbiosis with natural emulsifiers of the oil itself over newly formed globules of ultrasonic (US) dispersion was found. At an ultrasonic treatment power of 250 W for 10 min, a microemulsion with an average globule size of 123.4 nm was obtained. It is shown that an increase in the duration of ultrasonic treatment for more than 10 minutes does not have a significant effect on the stability of the obtained microemulsion of an ultramicroheterogeneous reagent
