METHOD OF PREPARING REAGENT FOR FLOTATION OF SULFIDE ORES Russian patent published in 1999 - IPC

Abstract RU 2142856 C1

FIELD: mineral dressing. SUBSTANCE: flotation reagent suitable for flotation of sulfide nonferrous ores, for example, copper-nickel ores is prepared by mixing xanthogenate with dithiocarbamate at weight ratio from 1:1 to 1:7 and adding 1-9 wt % of alkaline stabilizer, e.g. calcium oxide or sodium carbonate. EFFECT: increased storage stability of reagent and increased recovery of nickel into concentrate with reduced consumption of reagents. 2 tbl
