In recent years, the mining output of titanium resources in China has increased year by year, and coastal titanium sand ore is one of the important titanium resources in China. However, titanium ore is difficult to be directly used in industrial production because of its complex mineral composition and large amount of iron, vanadium and other impurities. Therefore, it is necessary to re select it to improve its grade and utilization value. This article will introduce a gravity separation experiment of coastal titanium sand ore, hoping to provide some reference for researchers and practitioners in related fields.
1、 Background of the experiment
Coastal titanium sand ore is a low-grade titanium ore. Its main minerals are Ilmenite, Magnetite, Hematite, etc. Because it contains a lot of iron, vanadium and other impurities, its grade is low and it is difficult to be directly used in industrial production. Therefore, it is necessary to re select it to improve its grade and utilization value.
2、 Test process
1. Preparation before the experiment
Before the experiment, it is necessary to collect and analyze samples of the coastal titanium sand mine to determine its mineral composition and chemical composition. At the same time, it is also necessary to prepare the equipment and reagents required for the experiment.
2. Test steps
(1) Grinding
Grind the collected samples of coastal titanium sand ore to obtain appropriate particle size.
(2) Rough selection
The sample after grinding shall be subject to rough separation, and gravity separator shall be used for gravity separation to separate heavy minerals such as Ilmenite and light minerals such as Magnetite and Hematite.
(3) Selected
The Ilmenite after rough separation shall be subject to intermediate separation, and the flotation method shall be used for flotation separation to remove iron, vanadium and other impurities.
(4) Selected
The Ilmenite after intermediate separation is cleaned and separated by magnetic separation and gravity separation to obtain high-grade Ilmenite.
3. Test results
After experimental treatment, the grade of coastal ilmenite has been significantly improved, among which the grade of Ilmenite has increased from 10% to 30%, and the content of iron, vanadium and other impurities has also been effectively removed.
3、 Experimental Conclusion
This gravity concentration test of coastal ilmenite has achieved good results, and successfully improved the grade and utilization value of Ilmenite. At the same time, the experimental results also provide valuable references and insights for researchers and practitioners in related fields. In the future, we will continue to conduct in-depth research and exploration, making greater contributions to the development and utilization of titanium ore resources in China.
