Processing technology of wolframite ore

Wolframite is an important tungsten ore, which is mainly used for extraction and processing of tungsten. The processing technology of wolframite is an important work in tungsten ore processing, which is of great significance for improving the recovery rate of tungsten and product quality. This paper will introduce the operation steps and precautions of wolframite processing technology. 1、 Operation steps of wolframite processing process 1 Crushing: Crush wolframite to make it suitable for processing. There are two methods of crushing: mechanical crushing and chemical crushing. 2. Grinding: grind the crushed wolframite to the required fineness. The methods of grinding ore include ball milling, rod milling, self milling, etc. 3. Flotation: Flotation of wolframite sand after grinding to separate impurities and non tungsten minerals from tungsten minerals. The methods of flotation include direct flotation, reverse flotation, mixed flotation, etc. 4. Dehydration: dehydrate the wolframite ore after flotation to remove the water in it and make it reach the required moisture content. The methods of dehydration include natural drying, centrifugal dehydration, and pressure filtration dehydration. 5. Drying: drying the dehydrated wolframite to make it reach the required moisture content. The methods of drying include natural drying, mechanical drying, microwave drying, etc. 2、 Precautions for wolframite processing technology 1 Pay attention to safety during the processing to avoid accidents. 2. Appropriate equipment and process shall be selected according to the hardness and particle size of wolframite sand during crushing and grinding. 3. During flotation, appropriate reagents and flotation process shall be selected according to the composition and properties of wolframite sand. 4. Appropriate equipment and process shall be selected according to the moisture content and particle size of wolframite during dehydration and drying. 5. During the processing, attention should be paid to environmental protection to avoid pollution to the environment. In short, the processing technology of wolframite ore is an important work in tungsten ore processing. We need to pay attention to safety and environmental protection, and select appropriate equipment and processes to improve the recovery rate of tungsten and product quality.
