Wolframite ore is an important tungsten ore, and tungsten is an important metal material, which is widely used in aviation, aerospace, electronics, photoelectric, chemical and other fields. Therefore, the mining and processing of wolframite is very important. This article will introduce the operation steps and precautions of the production line for mining and dressing wolframite ore.
1、 Basic situation of wolframite mining and dressing
Wolframite is a kind of ore with high tungsten content, whose main components are calcium tungstate and iron tungstate. The mining and dressing of wolframite ore are mainly carried out by gravity separation, flotation, magnetic separation and other processes. During the mining and selection process, the following points need to be noted:
1. Mineral processing index: the mineral processing index of wolframite refers to the tungsten content, recovery rate, grade and other indicators. During the mining and beneficiation process, adjustments and optimizations need to be made based on the beneficiation indicators.
2. Mineral processing technology: The mineral processing technology of wolframite mainly includes gravity separation, flotation, magnetic separation, etc. In the mining and beneficiation process, it is necessary to select appropriate beneficiation processes based on the properties and beneficiation indicators of the ore.
3. Equipment selection: a series of equipment are required for the mining and dressing of wolframite ore, such as crusher, ball mill, flotation machine, magnetic separator, etc. During the mining and beneficiation process, it is necessary to select appropriate equipment based on the beneficiation process and beneficiation indicators.
II. Operation steps of wolframite production line
1. Raw material crushing: wolframite ore needs to be crushed to meet the requirements of mineral processing. The crusher is a key equipment in the crushing process, and it is necessary to choose the appropriate model and specification.
2. Grinding: The crushed wolframite ore needs to be ground by a ball mill to meet the requirements of mineral processing. Ball mills are key equipment in the grinding process, and appropriate models and specifications need to be selected.
3. Gravity concentration: the wolframite sand after grinding treatment needs to be processed by gravity concentration to improve its grade and recovery rate. During the re selection process, a re selection machine is required for processing.
4. Flotation: wolframite ore after gravity separation needs flotation treatment to further improve its grade and recovery rate. The flotation process requires the use of a flotation machine for treatment.
5. Magnetic separation: the wolframite ore after flotation needs magnetic separation to remove the magnetic impurities. During the magnetic separation process, a magnetic separator is required for processing.
6. Tailings treatment: A large amount of tailings will be generated during the mining and selection process, and tailings treatment is required. Tailings treatment mainly includes processes such as drying and screening.
3、 Precautions for production line of wolframite ore mining and dressing
1. Adjustment of beneficiation indicators: During the mining and beneficiation process, it is necessary to adjust and optimize the beneficiation indicators to achieve better beneficiation results.
2. Equipment maintenance and upkeep: The mining and selection equipment needs to be regularly maintained and upkeep to ensure its normal operation and lifespan.
3. Safety production: During the mining and selection process, it is necessary to strictly comply with safety production regulations to ensure the personal safety of workers.
4. Environmental requirements: During the mining and selection process, it is necessary to strictly comply with environmental requirements to reduce pollution and waste.
In a word, the production line of wolframite ore mining and dressing is a complex process, and it is necessary to select appropriate beneficiation process and equipment according to beneficiation indexes and ore properties. During the mining and selection process, it is necessary to pay attention to safety production and environmental requirements to ensure the safety and environmental protection of the production process.
