Molybdenum ore processing process and beneficiation equipment
Molybdenum is a high-quality metal with high melting point, corrosion resistance and wear resistance. It is widely used in metallurgy, machinery, aerospace, national defense, building materials, electrical and other fields. It is known as the “war metal”. my country is rich in molybdenum resources, and its total reserves are among the top in the world, mainly distributed in Shaanxi, Liaoning, Henan, Guangdong, Hunan, Inner Mongolia and other places.
With the continuous improvement of global industrial technology, the molybdenum mining industry has attracted the attention of investors, and there are more and more friends who want to invest in the molybdenum mining market.
Necessary equipment for molybdenum ore processing technology
1. Molybdenum ore crushing equipment-jaw crusher
The quality of molybdenum ore crushing will have a certain impact on the grade of molybdenum concentrate. Therefore, the molybdenum ore crushing process usually adopts three-stage closed-circuit crushing. The equipment used is composed of jaw crusher + cone crusher + impact crusher, which can be better The realization of molybdenum ore crushing and partial dissociation work.
2. Molybdenum Ore Grinding Equipment-Ball Mill
Molybdenum ore grinding equipment generally uses molybdenum ore ball mills produced by Henan dewo rock stone crusher machines. This is a professional grinding equipment designed on the basis of the original ball mill and combined with the properties of molybdenum ore. It has better grinding effect, simple operation, and good energy-saving effect. Strong and durable, it can make molybdenum ore grinding more fully.
3. Molybdenum ore beneficiation equipment-flotation machine
The flotation method is usually used in the beneficiation stage of molybdenum ore, so the beneficiation equipment is mainly a flotation machine, and the corresponding chemical solvent is used to achieve a good effect of separating the molybdenum concentrate from other elements. The equipment is stable in operation, high in efficiency, high in yield, and low in carbon. Environmental protection and good flotation effect.
The process of molybdenum ore processing is usually divided into three stages, including crushing and screening, grinding and beneficiation. The beneficiation stage is the top priority of the entire process, so it needs to be paid special attention.
1. Molybdenum ore crushing stage
The large molybdenum ore is first sent from the silo through the vibrating feeder to the jaw crusher for preliminary processing (that is, coarse crushing); then it is divided into different levels by the circular vibrating screen, and the material that meets the requirements is on the belt conveyor Under the action, it is sent to the cone crusher evenly and orderly for re-crushing (referred to as middle crushing);
Similarly, after medium crushing, the qualified molybdenum mineral material will be sent to the impact crusher for further fine crushing treatment, and the material that does not meet the requirements will be sent back to the upper level for further crushing.
2. Molybdenum ore grinding stage
After finely crushing, qualified molybdenum ore particles (0-12mm) will be sent to the molybdenum ore ball mill for grinding processing. At the same time, a spiral classifier is required for classification. The unqualified molybdenum ore powder needs to be returned to continue grinding until it reaches the standard.
3. The beneficiation stage of molybdenum ore
The ground molybdenum ore fine powder will then enter the final stage-flotation. According to the composition of the molybdenum ore powder, different reagents are selected to achieve the separation effect in order to obtain the final high-grade molybdenum concentrate.
