Beneficiation technology of wolframite tailings

Wolframite is an important tungsten ore, which contains high tungsten, copper, lead, zinc and other metal elements, and is one of the important metal ores. The beneficiation technology of Wolframite is an important link in the mining and utilization of mines. Effective beneficiation technology can improve the grade and recovery rate of ores, reduce production costs and improve the economic benefits of mines.

Current Status of Mineral Processing Technology for Black Tungsten Tailings

Black tungsten tailings refer to the remaining ore after mineral processing, which contains lower levels of metal elements such as tungsten, copper, lead, zinc, etc. At present, the beneficiation technology of wolframite tailings mainly uses methods such as flotation, gravity separation, and magnetic separation for treatment. Among them, flotation method is the most commonly used method, which can effectively improve the grade and recovery rate of the ore, but its beneficiation effect is greatly affected by the impurities and mineral composition in the ore.

2、 Improvement of beneficiation technology for wolframite tailings

In order to improve the effectiveness of wolframite tailings beneficiation technology, it is necessary to improve it. On the one hand, the beneficiation effect of the flotation method can be improved by improving the flotation agent and adjusting the dosage of the agent. On the other hand, new beneficiation technologies such as oxidation roasting and cyanide leaching can be adopted for treatment to improve the grade and recovery rate of the ore.

1. Oxidation roasting method

Oxidation roasting method is a method of oxidizing and roasting black tungsten tailings, which can effectively separate and extract metal elements such as tungsten, copper, lead, zinc, etc. from the ore. This method requires crushing, screening, soaking, and other treatments of wolframite tailings before undergoing oxidation roasting. During the roasting process, the metal elements in the ore are oxidized into corresponding oxides, which are then separated and extracted through methods such as washing and soaking.

2. Cyanide leaching method

The cyanide leaching method is a method of cyanide leaching black tungsten tailings, which can effectively separate and extract metal elements such as tungsten, copper, lead, zinc, etc. in the ore. This method requires crushing, screening, soaking, and other treatments of wolframite tailings before cyanide leaching. During the leaching process, the metal elements in the ore are cyanide converted into corresponding ions, which are then separated and extracted through methods such as adsorption and precipitation.

Application of beneficiation technology for wolframite tailings

The application of black tungsten tailings beneficiation technology can improve the economic benefits of mines, reduce production costs, and also reduce environmental pollution. In practical applications, it is necessary to select appropriate beneficiation methods and reagents based on the characteristics of the ore and the requirements of the beneficiation process, and carry out reasonable operations and management to achieve the best beneficiation effect.

Conclusion

The beneficiation technology of wolframite tailings is an important link in mining and utilization. Effective beneficiation technology can improve the grade and recovery rate of the ore, reduce production costs, and improve the economic benefits of the mine. At present, the beneficiation technology of wolframite tailings mainly uses flotation, gravity separation, magnetic separation and other methods for treatment, but its beneficiation effect is greatly affected by impurities and mineral composition in the ore. In order to improve the beneficiation efficiency of wolframite tailings, methods such as improving flotation agents and adjusting the dosage of reagents can be used to improve the beneficiation efficiency of the flotation method. New beneficiation techniques such as oxidation roasting and cyanide leaching can also be used for treatment. In practical applications, it is necessary to select appropriate beneficiation methods and reagents based on the characteristics of the ore and the requirements of the beneficiation process, and carry out reasonable operations and management to achieve the best beneficiation effect.
