Application of cationic collectors - aliphatic amines and alkylmorpholines - has provided the world development of flotation technology for processing of water-soluble minerals. The results of research on the development of new reagents (foaming agents and depressors), which improve the performance of cationic flotation of ores and reduce the consumption of the collector, are presented. The directions of improvement of technological and logical schemes of potash ore processing are considered.
