Abstract

The invention discloses a Schiff base caproate mineral flotation collecting agent, a preparation method thereof and application thereof. A Schiff base caproate has an aliphatic group and a carbon-nitrogen double bond and carboxyl structure and is prepared by performing ammonia aldehyde condensation reaction on hydrolyzed caprolactam and aliphatic aldehyde. The Schiff base caproate has the characteristics of good water solubility, high dispersibility and high selective adsorption capacity to a target mineral, serves as the flotation collecting agent of bauxite, ilmenite, scheelite, wolframite, rare earth mine, tin ore, fluorite ore or manganese carbonate ore, and can effectively float and separate available minerals; furthermore, the preparation method of the Schiff base caproate is simple in process, easy in control on operation, low in cost, and high in product yield, and industrial production is easy to realize.

Description

technical field

[0001] The invention relates to a Schiff base hexanoate mineral flotation collector and a preparation method and application thereof, belonging to the field of mineral flotation. 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 ore 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. Chinese patent (publication number is CN102921537A) discloses a kind of method of flotation limonite with oleic acid; The collector that forms is used for the method of ilmenite, iro...
