Abstract
Studies on the flotation enrichment of polyhalite-halite ore have been carried out. It was determined that the maximum degree of disclosure of polyhalite-halite ore to the components during grinding falls on the fraction (–0.5 mm). It was established that the enrichment of polyhalite-halite ore is possible by the method of reverse flotation using alkylmorpholine as a collector. It was established that high levels of enrichment of polyhalite-halite ore (recovery of halite 95.41 %) are achieved at high dosage of the collector (1600 g/t).
