METHOD OF POTASSIUM ORES FLOTATION Russian patent published in 2001 - IPC

Abstract RU 2165797 C1

FIELD: technology of mineral processing by method of potassium ores flotation. SUBSTANCE: method includes grinding of ore, treatment of ore with flocculant and collecting reagent, slime and flotation, flotation of potassium chloride with use of collector in the form of primary aliphatic amines. Collecting reagent for flotation of slimes is used in the form of oxyethylated alkylphenols with length of hydrocarbon radical C₂ and 12-20 ethox groups in radical produced on base of propylene trimers. EFFECT: higher efficiency of ore desliming, reduced consumption of reagents and improved flotation characteristics of useful mineral. 2 ex
