Combined collecting agent used for conducting flotation on pyroxene peridotite type ilmenite, preparation method and application

Abstract

The invention provides a combined collecting agent used for conducting flotation on pyroxene peridotite type ilmenite. The combined collecting agent is composed of a component A, a component B and water. The component A is oleic acid or oxidized paraffin soap. The component B is primary amine hydrochloride or quaternary ammonium salt. The weight ratio of the component A to the component B ranges from 9:1 to 12:1. The weight ratio of the sum of the weight of the component A and the weight of the component B to the weight of the water is 1:(4-19). The raw ore grade of the pyroxene peridotite type ilmenite is not higher than 18%. The invention further provides a preparation method and application of the combined collecting agent. The flotation index achieved through the combined collecting agent is good, the number of required concentration times is small, and the quantity of the agent which is used is small; and meanwhile the requirement of the collecting agent for flotation conditions is loose, and the combined collecting agent has good hard water resistance.

Description

technical field [0001] The invention belongs to the technical field of mineral processing engineering, and in particular relates to a combined collector for flotation of olivine pyroxenite-type ilmenite, a preparation method and application. Background technique [0002] With the rapid development of my country's titanium industry and the rise of titanium dioxide industry, my country's demand for titanium concentrate is increasing. The largest ilmenite rock deposit in China is in the Panxi area of ​​Sichuan, but after decades of exploitation of the titanium magnetite resources in this area, most of the mines have entered the middle and deep mining. As the four major mining areas in Panxi (Panzhihua, Hongge, Baima, and Taihe) are mined deeper, the proportion of gabbro and pyroxenite gradually decreases, while the proportion of olivine pyroxene and peridotite gradually increases. This type of olivine-type titanomagnetite contains a large amount of gangue minerals such as oliv...

AI Technical Summary

Problems solved by technology

This type of olivine-type titanomagnetite contains a large amount of gangue minerals such as olivine, titanopyroxene, chlorite and hornblende, etc., and the mineral composition is complex

At the same time, because these gangue minerals are similar to the useful mineral ilmenite in floatability, using traditional flotation reagents to flotation them has poor selectivity and low recovery, and it is difficult to obtain better industrial beneficiation indicators.

[0003] Although some collectors for ordinary ilmenite have been successfully developed, these collectors are either difficult to obtain higher-grade titanium concentrates, or the recovery rate is low when obtaining higher-grade titanium concentrates (above 45%). lower

In addition, the preparation system of these collectors is too complicated, and emulsifiers are often required, and the dosage of agents is relatively large

As the preparation system of the collector announced by CN 105583084 A is complicated, and requires a large amount of lye harmful to the environment, the recovery rate of the collector of this patent is low, no more than 82%; The preparation system of the collector is not only complicated, but the recovery rate is only more than 60%; as the collector disclosed in CN102489410 B, the preparation system is not only complicated, but also in order to obtain higher grade and recovery rate, it needs to go through one thick three fines after floating sulfur. Operation, the procedure is comparatively complicated; As the collector disclosed by CN 104117435 A not only has a complicated preparation system, but the selection times need more than three times and the recovery rate is low; although the collector provided by CN 102600985 A has a relatively simple preparation system, it cannot Minor increase in concentrate grade and lower sulfuric acid usage, but recovery remains low
