Abstract

The invention discloses a non-sulfide mineral flotation collector, a preparation method thereof and an application thereof, and belongs to the technical field of mineral flotation collectors. The non-sulfide mineral flotation collector is obtained by mixing phosphoric acid-2-ethylhexyester or / and 2-ethylhexyl phosphoric acid-2-ethylhexyl ester and sodium oleate or oxidized paraffin soap and the like for use. The non-sulfide mineral flotation collector has the characteristics of good water solubility, good dispersion, strong selective adsorption capacity on target minerals and the like, and is mainly used for floatation separation of useful minerals in ilmenite, scheelite, wolframite, phosphorite, bauxite, rare earth ores, tin ores, fluorite mines or manganese carbonate ores. The preparation method for the non-sulfide mineral flotation collector is simple in process, easy to control in operation, wide in raw material source, low in cost, safe and environmentally-friendly, high in product recovery rate, and easy to realize industrial production.

Description

technical field [0001] The invention belongs to the technical field of mineral flotation collectors, and in particular relates to a non-sulfide mineral flotation collector and its preparation method and application. Background technique [0002] Fatty acids and their soaps, because they contain active carboxyl functional groups, can effectively separate useful minerals from gangue, and are a class of excellent non-sulfide mineral flotation collectors. Since higher fatty acids are solid at room temperature, difficult to dissolve in water, and inconvenient to use, oleic acid, linoleic acid, linolenic acid, tall oil fatty acid and liquid saturated fatty acid are commonly used, and are currently the most commonly used in industrial flotation processes. It is oleic acid and its modified products and oxidized paraffin soap. The Chinese patent (publication number is CN102600985A) discloses a method for the flotation of ilmenite and iron oxide ore with a collector made of oleic aci...
