REAGENTS FOR BENEFICIATING ORES

摘要

Flotation concentration of sylvite from sylvinite or other potassium chloride ores in a brine of the ore, particularly effective where brine carrier is dirty or at high temperature. Small amounts of silicone polymers are introduced as auxiliary agents in conjunction with primary aliphatic amines and aliphatic and/or aromatic oils as collectors reducing total reagent requirement with resulting cost reduction and substantial improvement in flotation efficiency.
