Mineral collecting agent for collecting oxidized ores such as fluorite and preparation method thereof

Abstract

The invention provides a mineral collecting agent for collecting oxidized ores such as fluorite and a preparation method thereof, and belongs to the technical field of a mineral flotation collecting agent. The mineral flotation collecting agent for the oxidized ores such as fluorite is obtained by mixing Medialen, specific carbon atom fatty acid, hydroximic acid, methyl isobutyl carbinol, a surface active agent and the like, and then is used. The mineral flotation collecting agent has the characteristics of good water solubility, good dispersibility and strong preferential adsorption capacityof a target mineral, and is mainly used for flotation separation of useful minerals in the oxidized ores such as the fluorite, calcite, barite and ilmenite. A preparation method of the mineral flotation collecting agent for the oxidized ores has simple process and is easy in control of operation; and the prepared collecting agent has the advantages of strong selectivity, good dispersibility, lessdosage of chemicals, high overall efficiency of beneficiation and the like, and is of great significance for promoting the beneficiation of the minerals such as the oxidized ores.

Description

technical field [0001] The invention relates to a flotation collector for oxidized ore minerals such as fluorite, and belongs to the technical field of mineral flotation collectors. Background technique [0002] Fluorite is an important raw material for the fluoride industry, so with the large-scale development of my country's fluoride industry, the demand for fluorite has also risen sharply. my country is rich in fluorspar resources, but the grade of fluorspar is generally low, generally 35-40%, so it needs to be enriched by flotation, so that the grade of fluorspar can meet the requirements of relevant industries and can be used. [0003] The general characteristics of my country's fluorite mineral resources are more lean ore, less rich ore, more difficult ore, less easy ore, more symbiotic ore, and less single ore. Over the years, my country's mineral processing technology and equipment have been backward, and the technical level is low. The extraction rate of non-metall...

AI Technical Summary

Problems solved by technology

[0005] Fluorite and scheelite have similar surface electrical properties and flotation behavior. The existing technology of fluorite flotation separation and recovery has the following technical defects: under the condition of high alkaline pH value and adding a large amount of water glass, fluorite is preferentially flotation. Strong inhibition makes the subsequent fluorite flotation extremely difficult, and it is difficult to increase the recovery rate of fluorite

When performing fluorite flotation, it is necessary to add a large amount of acid and activator to adjust the pH value of the pulp, and activate part of the gangue minerals when activating the suppressed fluorite minerals, making it difficult to improve the quality of fluorite flotation concentrates

The process of fluorite beneficiation is complex, multiple beneficiation is required, tailings must be discharged twice during the beneficiation process or concentrate regrinding is required to ensure the grade of fluorite concentrate, the on-site production beneficiation control is difficult and the stability is poor

Mixed flotation of tungsten and fluorite is used, and the process of separation flotation of mixed concentrate - regrinding and re-election - acid leaching - tungsten gravity recovery and other complicated processes

A large amount of water glass is added during flotation, and there is also the problem of low flotation recovery rate after fluorite is suppressed
