COLLECTOR FOR FLOTATION OF SILICATE AND CARBONATE MINERALS FROM POTASSIUM-CONTAINING ORES Russian patent published in 1998 - IPC

FIELD: mineral concentration; may be used at potassium industry enterprises for preliminary flotation of water-insoluble minerals from potassium ores. SUBSTANCE: compound of quaternary hydrazine salt with respective chemical formula is used as collector for ore flotation. Salt was used in the form of aqueous emulsion. Application "Hidrazeksa-2" (commercial name) offers the following advantages over the used collectors at present time: reduced harmful effect on environment due to use of flotation agent less soluble in water and its lower consumption.
