Abstract

The invention relates to a collophanite normal-temperature flotation collector, in particular to collophanite flotation collector prepared from natural rubber seed oil fatty acid, belonging to the collector. The invention also relates to a method for preparing the collophanite flotation collector. The collophanite flotation collector comprises natural rubber seed oil fatty acid, tall oil, tributyl phosphate, tween 80, dodecyl benzene sulfonic acid, inorganic base and water. The collophanite flotation collector has stable chemical performance, good water solubility, high flotation speed, suitable viscosity and strong selectivity and collection performance, is easy to diffuse in collophanite pulp, can be used for obverse floatation and reverse flotation and can generate uniform bubbles, obviously shorten the floatation time, improve the concentrate grade and reduce the content of impurities in the concentrate product.

Description

Technical field [0001] The invention relates to a collector, in particular to a collophanite flotation collector prepared by using natural rubber seed oil fatty acid, and the invention also relates to a preparation method of the collector. Background technique: [0002] Early collectors for phosphate rock flotation commonly used tall oil and its saponified compounds. In addition, oxidized paraffin soap, oleic acid and its sodium salt, etc. were also used. These fatty acids and their salts generally have a collecting effect, but they have poor selectivity. , The shortcomings of large dosage and need to heat the pulp. Since the 1980s, some more effective collectors for phosphate rock flotation have been developed at home and abroad, such as: modified fatty acids, ether amines, amphoteric collectors, amide carboxylic acid collectors, phosphate esters and organic Phosphoric acid, cationic amine collector. Due to the differences in phosphate ore in different regions, even in the sam...
