Problems solved by technology

However, the selection of active ingredients used in the desulfurization agent for the retaining wall is relatively strict and harsh, and the collector used is a specific collector component, resulting in a higher cost of the agent, resulting in a higher cost in the process of beneficiation and desulfurization

Embodiment Construction

[0015] The technical solutions of the present invention will be further limited below in conjunction with specific embodiments, but the scope of protection is not limited to the descriptions made.

[0016] In the following tests, the high-sulfur magnetite ore beneficiation agent used was prepared and stored separately after the mixed solution was prepared; when the collection liquid was used, it was prepared now, and after the preparation was completed, it was added to the mixed solution and used immediately Flotation removes pyrrhotite in high-sulfur iron concentrate; the preparation process includes the steps of preparing the mixed solution, preparing the collecting liquid, mixing the mixing liquid and collecting the liquid; the step of preparing the mixed solution is After mixing citric acid, tartaric acid and iron sulfide evenly, add them into water, and stir them evenly to obtain the product; the preparation step of the collection medicinal solution is to mix ethiazide, so...

Abstract

The invention relates to the technical field of mineral processing chemicals, in particular to a high-sulfur magnetite processing agent and an application method thereof. The high-sulfur magnetite processing agent is prepared by the following steps: using citric acid, tartaric acid, iron sulfide and water to prepare a mixed solution; using sodium diethyldithiocarbamate, sodium sulfide, ammonium dibutyl dithiophosphate and water to prepare a collecting agent liquid; and mixing the mixed solution and the collecting agent liquid according to a volume ratio of 1:(0.3-1.8) to form the high-sulfur magnetite processing agent. Therefore, activation of pyrrhotite is realized, separation between the pyrrhotite and magnetite is ensured, and the purpose of enhancing the desulfurization effect is achieved. The high-sulfur magnetite processing agent can be applied to desulfurization treatment of high-sulfur magnetites with different sulfur contents, and enables the sulfur content of iron concentrateafter flotation treatment to be reduced 0.15% or less, and the iron concentrate yield to be 91% or more.

Description

technical field [0001] The invention relates to the technical field of beneficiation agents, in particular to an agent for beneficiation of high-sulfur magnetite ore and an application method thereof. Background technique [0002] The iron and sulfur reduction of high-sulfur magnetite ore usually adopts the combined process of grinding-magnetism-flotation, that is, the raw ore is firstly ground to a suitable grinding particle size, and the tailings are firstly separated by weak magnetic separation to obtain magnetite concentrate with qualified iron grade , and then carry out reverse flotation desulfurization on the magnetite concentrate. The sulfur in high-sulfur magnetite mainly exists in the form of pyrrhotite, and its desulfurization problem has been one of the important factors restricting the development of iron and steel enterprises for a long time, and has become a common problem faced by the entire industry. In order to make full use of iron ore resources with high ...
