Abstract
The material constitution and structure of mineral particles in fluorite ore mill waste at Yaroslavskaya Mining Company are estimated. The set of factors having influence on the efficiency of sample preparation for flotation is determined. Alongide with the complex mineralogy and structure of primary ore, dressability of mining waste is affected by mineral properties acquired in prime processing and during long-term tailings storage. It is necessary to take care when selecting the process conditions and the composition of agents for flotation. The studies into the influence exerted on flotation performance by a composiiton of carboxyl collectors with different contents of fat acids and different structures of hydrocarbon radical identified the best effective conditions. It is feasible to produce finely dispersed carbonate-fluorite concentrates from mining waste, at CaF2 content of 95.21-95.6% and at fluorite recovery of 59.55-62.56%.
