Abstract
The authors describe studies into dressability of mill tailings from tailings pond of processing plant of Yaroslavsky Mining Company. It is found that the mill tailings contain 14.92% of CaF2, 13.16% of CaCO3 and 0.49% of Zn. The use of new compositions of modifiers in flotation of fluorite allows production of standard grade concentrates with CaF2 content of 93.19–95.54% at the recovery of 52.75–30.15%. Zinc recovery is 38.84% with the yield of 42.11% Zn concentrate.
