Iron mine oxidized ore flotation green collector and production process thereof

Abstract

The invention relates to an iron mine and oxidized ore beneficiation and flotation agent and a production method thereof and specifically discloses an iron ore and oxidized mine flotation anion collector; the main preparing agents of the anion collector are fatty acid modifier and derivatives thereof; assisting agents of the collector also comprise fatty alcohol, emulsifier and water. The production method of the collector comprises the following steps of compounding the main agents by organic action, then weighting rest components according to certain mass fractions, mixing according to a certain sequence, and uniformly stirring to prepare the micro-emulsion homogeneous phase viscous liquid. The collector has the advantages of strong collecting capacity, strong argillization resistance, low production cost, hard water resistance, stable performances, small agent use level, good selectivity, environment friendliness, safety and adaptivity to low temperature. By changing the variety and use level of the main agents, the series of collectors can be used for the flotation of diversified iron mines, phosphorite mines, fluorites, tungsten mines, rare earth mines, ilmenites and diversified oxidized mines.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency utilization of mineral resources, and in particular relates to a flotation reagent for beneficiation of iron ore and various oxidized ores, a preparation method and application thereof. Background technique [0002] Mineral resources are one-time resources and are non-renewable. Due to years of mining and utilization, all kinds of rich ore resources in the world are decreasing day by day. Refractory minerals will become more and more important. Most ore resources in my country generally have the characteristics of "poor, fine, miscellaneous" and high impurity content, while high-quality "ore concentrate" has broad application prospects and broad market prospects, which objectively requires the concentrator to choose a reasonable capture Collector and its flotation process to produce high-quality concentrate, so as to achieve maximum economic benefits and save resources. Not only that, hig...

AI Technical Summary

Problems solved by technology

China's iron ore resources are relatively poor, especially compared with Brazil and Australia, the main iron ore exporting countries, my country's iron ore resources have the following obvious deficiencies: ①The average raw ore grade is low; ②The proportion of rich ore is relatively small; ③SiO 2 ④ Iron ore contains phosphorus, sulfur and arsenic exceeding the standard; ⑤ A large number of iron-containing tailings have low re-election rate and serious waste of resources

Due to the poor dispersion of fatty acid soaps in the pulp, it is often necessary to heat the pulp for heating flotation, and the energy consumption is high

Cationic chemicals are very sensitive to ore slime, and the beneficiation index is unstable
