Wolframite quartz gravity concentration

Wolframite quartz is an important tungsten ore and one of the main sources of tungsten resources. In the mining process, the recovery rate and grade of Wolframite quartz are important factors that affect the mining efficiency of tungsten ore. Therefore, the research and application of Wolframite quartz gravity concentration technology is of great significance.

1、 Characteristics of Wolframite quartz

Wolframite quartz is a tungsten ore with high hardness, high density and dark color. Its main components are calcium tungstate, quartz, Galena, etc. The grade of Wolframite quartz is generally low, usually about 0.3%~0.5%, and contains many impurities, such as iron, copper, lead, zinc, etc.

2、 Principle of gravity separation of Wolframite quartz

The principle of gravity concentration of Wolframite quartz is to separate Wolframite quartz from other minerals by mineral processing equipment according to the difference in physical and chemical properties of Wolframite quartz and other minerals, so as to improve the grade and recovery rate of Wolframite quartz.

The main steps of Wolframite quartz gravity separation include crushing, grinding, flotation, tailings treatment, etc.

3、 Operation steps of Wolframite quartz gravity concentration

1. Crushing: preliminarily crush the Wolframite quartz ore to make its particle size meet the requirements for grinding.

2. Grinding: finely grind the crushed Wolframite quartz to further refine its particle size for flotation separation.

3. Flotation: the Wolframite quartz after grinding is separated by flotation. Generally, the Copper(II) oxide flotation method is used. The Wolframite quartz and other minerals are separated by controlling the type and amount of flotation reagents.

4. Tailings treatment: the flotation tailings are treated by gravity separation, magnetic separation and other methods to further recover the Wolframite quartz in the tailings and remove the impurities therein.

IV. Application of Wolframite quartz gravity concentration

The application of Wolframite quartz gravity concentration technology can improve the grade and recovery rate of Wolframite quartz, thus improving the mining efficiency of tungsten ore. At present, Wolframite quartz gravity concentration technology has been widely used in tungsten ore mining and processing, and has achieved good results.

In a word, Wolframite quartz gravity concentration technology is an important technical measure, which can improve the mining efficiency of tungsten ores and has broad application prospects.
