METHOD OF ORES FLOTATION Russian patent published in 2015 - IPC B03D1/02

Abstract RU 2564549 C1

FIELD: mining.

SUBSTANCE: ore flotation comprises ore crushing, ore flotation desludging and sylvite flotation. Flocculent and sludge collector are fed to sludge flotation feed as a combined solution. The latter is produced by premixing of the solutions of polyacrylamide flocculent and oxyethylated sludge collector (oxyethylated amines, or phenols, or alcohols) containing the hydrocarbon radical of at least 19 and not over 65 moles (groups) of oxyethylene. Combined solution of flocculent and sludge collector is produced by combined dissolution of polyacrylamide and sludge collector in water. Combined solution of flocculent and sludge collector is produced by dissolution of polyacrylamide in sludge collector solution.

EFFECT: higher flotation ability of slimes from potassium ore, decreased amount of slimes in sylvite flotation feed.
