Exploratory application of novel flotation agent at Chaochuan Coking Coal Preparation Plant

In order to improve the flotation performance, industrial test is made on the flotation of the fine coal of the plant using novel FQB-I frother and FMD-II collector, and the result obtained is compared with the process of using kerosene and heteroalcohole. As evidenced by test result, with the use of FQB-I and FMD-II and the addition of kerosene in FMD-II at a volume ratio of 20%, a much improved flotation result with less consumption of reagent and consistency of concentrate quality can be obtained.
