Abstract

The invention discloses a preparation method and application of a non-molybdenum sulfide mineral flotation and separation inhibitor. The preparation method for the flotation and separation inhibitor comprises the step of enabling phosphorus pentasulfide and alkaline compounds to react with water-soluble macromolecules, and thus the flotation and separation inhibitor can be obtained. According to the preparation method for the non-molybdenum sulfide mineral flotation and separation inhibitor, operation is easy, the process conditions are mild, the raw material cost is low, and the industrial production requirements are met; and moreover, the prepared product directly serves as the non-molybdenum sulfide mineral inhibitor applied to flotation and separation of molybdenum sulfide minerals and non-molybdenum sulfide minerals, the molybdenum sulfide minerals and the non-molybdenum sulfide minerals can be effectively separated, the grade of molybdenum concentrates is improved, and the flotation and separation inhibitor is particularly suitable for flotation and separation of molybdenite, copper sulfide ore, galena, pyrite, jamesonite, arsenopyrite, bismuth sulfide ore and the like.

Description

technical field [0001] The invention discloses a preparation method and application of a non-molybdenum sulfide mineral flotation separation inhibitor, in particular to a non-molybdenum sulfide mineral separation inhibitor, which is used for molybdenum concentrate containing pyrite, primary copper sulfide ore, secondary Sulfide minerals such as copper sulfide, galena, pyrite, arsenopyrite and bismuth sulfide have a strong inhibitory effect. After adding this inhibitor, molybdenum sulfide ore can be effectively separated from non-molybdenum sulfide minerals, and high-quality molybdenum sulfide can be obtained. concentrate. Background technique [0002] Copper-molybdenum sulfide associated ore is generally obtained by copper-molybdenum mixed flotation to obtain copper-molybdenum mixed concentrate, and then the copper-molybdenum minerals are separated by the method of copper-suppressed floating molybdenum or molybdenum-suppressed floating copper to obtain copper concentrate and...
