Mining technology of wolframite ore

Wolframite ore is an important tungsten ore, which contains more than 60% tungsten and is an important part of tungsten resources in the world. The mining technology of wolframite ore refers to a series of technological processes such as mining, beneficiation and tungsten extraction of wolframite ore. This paper will introduce the operation steps and precautions of wolframite ore mining technology in detail. 1、 Wolframite mining wolframite mining is the first step of wolframite mining technology, its purpose is to extract wolframite from underground or surface. The mining of wolframite ore mainly includes Surface mine mining and underground mining. 1. Surface mine Surface mine refers to the way of mining wolframite on the surface. Its advantages are high mining efficiency, low cost, and suitable for deposits with high tungsten content. However, Surface mine will have a certain impact on the environment, which requires environmental protection. 2. Underground mining refers to the underground mining of wolframite. Its advantages are small environmental impact, but low mining efficiency and high cost, making it suitable for deposits with low tungsten content. In underground mining, support and ventilation work are required to ensure mining safety. 2、 Wolframite ore dressing wolframite ore dressing refers to the process of separating, impurity removal, flotation and other processes of wolframite ore obtained from mining to extract tungsten concentrate. The dressing of wolframite ore mainly includes hand dressing, gravity dressing and flotation. 1. Hands selection refers to the method of separating impurities in wolframite sand from tungsten minerals by manual visual inspection, hand touch, etc. Manual selection is applicable to wolframite ore with high tungsten content and large particle size, but it has low efficiency and high cost. 2. Gravity separation Gravity separation refers to the separation of impurities in wolframite sand from tungsten bearing minerals by gravity separation, magnetic separation, etc. Gravity separation is applicable to wolframite ore with low tungsten content and small particle size, but it requires multiple separation and has high cost. 3. Flotation Flotation refers to the separation of impurities in wolframite sand from tungsten bearing minerals by means of bubble adsorption, mineral surface chemical reaction, etc. Flotation is suitable for wolframite ore with low tungsten content and small particle size, but it requires reagent adjustment, equipment maintenance and other work, which is costly. 3、 Extraction of tungsten from wolframite and wolframite refers to the process of smelting and purifying the tungsten bearing concentrate obtained from ore dressing to obtain pure tungsten or tungsten alloy. Extraction of tungsten from wolframite ore mainly includes thermal method and wet method. 1. Thermal method refers to the method of extracting tungsten from tungsten containing concentrates through high-temperature melting, distillation, and other methods. The thermal method is suitable for tungsten containing concentrates with high tungsten content and low impurities, but requires equipment maintenance, energy consumption, and other work. 2. Wet wet method refers to the process of extracting tungsten from tungsten containing concentrates through chemical reactions, dissolution, precipitation, and other methods. Wet method is suitable for tungsten containing concentrates with low tungsten content and high impurities, but requires adjustments to reagents and equipment maintenance. To sum up, the mining process of wolframite ore is a complex process, which requires mining, beneficiation, tungsten extraction and other links. During the operation process, attention should be paid to environmental protection, mining safety, and other issues to ensure the smooth progress of the process.
