Tungsten ore is an important metal ore with characteristics such as high density, high melting point, and high wear resistance. It is widely used in fields such as aviation, aerospace, electronics, and chemical engineering. However, there are many technical difficulties in the mining and beneficiation process of tungsten ore, among which the most critical is the treatment of beneficiation soil. This article will introduce the beneficiation methods of tungsten ore, helping readers understand the beneficiation process of tungsten ore.
1、 Overview of beneficiation methods for tungsten ore
Mineral processing soil refers to a substance that extracts tungsten from tungsten ore, mainly including flotation soil, gravity soil, and mixed soil. The main methods for beneficiation of tungsten ore are as follows:
1. Flotation method: After crushing and grinding tungsten ore, adding reagents, and using bubbles to separate tungsten minerals from the ore, forming flotation soil.
2. Gravity separation method: After the flotation soil is subjected to gravity separation and grinding, tungsten minerals are separated from the flotation soil by gravity to form gravity separation soil.
3. Mixing method: Mix flotation soil and gravity soil together, grind them fine, and use bubbles and gravity to separate tungsten minerals from the mixed soil.
2、 Operation steps of flotation method
Flotation method is one of the main beneficiation methods for tungsten ore, and its operating steps are as follows:
1. Ore crushing: preliminarily crush tungsten ore to make it reach Granularity suitable for flotation.
2. Reagent addition: add reagent to the pulp and adjust the pH value of the pulp to make it suitable for flotation.
3. Bubble entry: the bubbles are put into the pulp to interact with tungsten minerals to form flotation foam.
4. Separation: Tungsten minerals are separated from ores by flotation foam to form flotation soil.
III. Operation steps of reselection method
Gravity separation method is another beneficiation method for tungsten ore, and its operating steps are as follows:
1. Flotation soil grinding: grind the flotation soil to Granularity suitable for gravity separation.
2. Gravity separation: Use gravity to separate tungsten minerals from flotation soil, forming a gravity separation soil.
3. Concentration: Concentrate the selected soil to achieve a certain tungsten content standard.
Operation steps of the mixed method
The mixing method involves mixing flotation soil and gravity soil for beneficiation, and the operating steps are as follows:
1. Mixing of flotation soil and gravity selected soil: Mix the flotation soil and gravity selected soil in a certain proportion.
2. Grinding: grind the mixed soil to Granularity suitable for beneficiation.
3. Bubble entry: the bubbles are put into the pulp to interact with tungsten minerals to form flotation foam.
4. Separation: use flotation foam and gravity to separate tungsten minerals from mixed soil.
5、 Summary
The beneficiation method of tungsten ore is an important link in the process of tungsten mining and utilization. The flotation method, gravity separation method, and mixing method are the main methods for tungsten ore beneficiation, with different operating steps, but the purpose is to separate tungsten minerals from the ore. For the mining and utilization of tungsten ore, the treatment of beneficiation soil is crucial. Only by adopting correct beneficiation methods and operating steps can better beneficiation results be achieved.
