Method for separating titanium, iron ore

Abstract

The invention belongs to a method for separating iron ore and titanium ore, comprising the steps of crushing, ball milling by one time and two times, magnetic separation with low strength, magnetic separation with high strength, ball milling by the third time, spiral separation and fine selection, magnetic separation with low strength and titanium reselection and the like so as to obtain 45 percent to 55 percent of titanium fine powder. The method can effectively separate the iron and the titanium in the iron ore and the titanium ore and has the advantages of simpleness, easy operation, simple technique, high purity, low cost, high efficiency, energy-saving and emission reduction, and greatly improving the utilization ratio of the iron ore and the titanium ore, and overcomes the defect that in the existing iron ore and the titanium ore, only iron is extracted and the contained rare metal of titanium can not be utilized, thus greatly improving the social and economical benefits and utilizing the limited mineral resources of China fully.

Description

technical field [0001] The invention belongs to a method for separating titanium and iron ore. Background technique [0002] Titanium and its alloys have excellent properties such as low density, corrosion resistance, and high temperature resistance. The world's titanium industry is undergoing a transition from a single model with aerospace as the main market to a multi-model that focuses on the development of metallurgy, energy, transportation, chemical industry, biomedicine and other civilian fields. At present, only a few countries such as the United States, Japan, Russia, and China are able to carry out titanium industrial production in the world. The annual world output of titanium is only tens of thousands of tons. It will become the "third metal" rising after iron and aluminum, and the 21st century will be the century of titanium. [0003] The current production method of titanium adopts the metal thermal reduction method, mostly using high temperature of 24000-4000...

AI Technical Summary

Problems solved by technology

At present, domestic scientific research personnel have failed to achieve success through a large amount of investment and research experiments, resulting in a large waste of resources, especially since 2003, nearly a hundred mines in this area can only extract iron from ilmenite, and the rare metals such as titanium contained in it All are discarded as waste, and titanium metal has not been extracted and utilized
