Improvement of the reagent regime for the flotation enrichment of polyhalite ores

Abstract

The effect of foaming agents of different chemical nature (amyl alcohol, glycolic ether, pine oil) on the flotation of halite from polyhalite ores using alkylmorpholine as a collector was investigated. It was established that the combined adding of amyl alcohol with alkylmorpholine and glycolic ether with alkylmorpholine in the process of sodium chloride flotation allows achieving high technological performance and reduces the consumption of expensive alkylmorpholine by 2 times. The use of pine oil as a foaming agent in a mixture with alkylmorpholine has been established to reduce the collector consumption by 2.2 times.
