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

Abstract

The invention relates to an iron ore concentrating flotation drug and a preparation method thereof and in particular discloses an iron ore flotation anion / cation collector. In the invention, a main agent for preparing an anion collector comprises fatty acid and a derivative thereof, and a main agent for preparing a cation collector comprises organic amine and / or a quaternary ammonium salt; and auxiliary agents of the two collectors also comprise an organosilicon compound, chloralkane, fatty alcohol, an emulsifier and water, wherein the auxiliary agent of the anion collector also comprises hydrocarbon oil. The preparation method of the collectors comprises the following steps of: synthesizing the main agents through organic reactions; weighing other components according to certain weight parts; mixing according to a certain sequence; and uniformly stirring to prepare micro-emulsion homogeneous phase viscous liquid. The collectors have the advantages of strong collecting capacity, high anti-argillization capacity, low production cost, hard water resistance, stable property, small drug dosage, good selectivity, environmental protection, safety, low temperature adaptability, and the like.

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 agent for iron ore beneficiation and a preparation method thereof. Background technique [0002] The world's rich iron ore resources are decreasing day by day, but due to the increasing demand for steel in industry, agriculture and other industries, the use of lean iron ore and refractory iron ore will become more and more important. my country's iron ore resources generally have the characteristics of "poor, fine, and miscellaneous". At the same time, SiO 2 High iron content, weak magnetic iron ore, and high-quality "iron concentrate" has broad application prospects and broad market prospects, which objectively requires the concentrator to choose a reasonable collector and flotation process to produce high-quality iron ore Concentrate, so as to achieve maximum economic benefits. Not only that, high-quality "iron ...
