Introduction of Zinc Ore beneficiation plant
The minerals in zinc ore are mainly sphalerite, iron sphalerite, sphalerite, and xenolite. The zinc sulfide mineral is sphalerite, and the main zinc oxide minerals are sphalerite and xenolite. The zinc ore beneficiation process adopts the flotation process.
China has extremely abundant zinc ore resources, with proven zinc reserves ranking among the top in the world. However, with the continuous development and utilization of mineral resources, there are fewer and fewer easily selected sulfide zinc ores. Choosing suitable zinc ore beneficiation processes is becoming increasingly important for improving zinc ore recovery rates. The beneficiation methods for fluorite ore are gravity separation and flotation, which are also divided into gravity separation equipment and flotation equipment. Gravity separation equipment refers to jigs, and only jigs can process coarse-grained fluorite ore. Fluorite flotation equipment is similar to other mineral flotation equipment, including crushers, ball mills, flotation machines, etc.
About the Processing on Zinc ore:
sphalerite |
The floatability of sphalerite largely depends on the impurities it contains, especially the iron content. Generally speaking, sphalerite is a sulfide mineral that is difficult to float, especially iron rich sphalerite; However, cadmium containing sphalerite is prone to flotation, and it has been reported that some cadmium containing sphalerite can be floated without the use of collectors.
The treatment method of mineral surface has a significant impact on the natural floatability of sphalerite. Research has found that sphalerite produced by ceramic ball mills exhibits a certain degree of natural floatability, while sphalerite produced by wet grinding with steel ball mills loses its natural floatability. |
smithsonite |
High grade yellow medicine or fatty acid collectors can be used for direct flotation recovery of smithsonite, but the selectivity is very poor. Sodium sulfide treatment is commonly used in industrial production, followed by flotation with amine collectors such as octadecylamine or mixed amines.
Research has shown that unlike galena, after treatment with sodium sulfide, smithsonite does not form a sulfide phase on its surface, but increases the negative charge on the surface of smithsonite, which is beneficial for the adsorption of cationic collectors and causes it to float. |
Introduction of flotation beneficiation plant
Flotation beneficiation is a sorting method based on different physical and chemical properties of the mineral particles. Flotation is widely used in fine-grained disseminated metallic minerals, nonmetallic minerals, chemicals and other mineral sorting.
Main process of flotation production line:
1. Ore crushing
2. The crushed material was sent to ball mill for grinding.
3. Classified . Granule with unsuitable size will be sent back to the ball mill , while suitable ones will be sent to the flotation system.
4. Some medicament agent will be added to separate target material from others.
5. After going through the flotation system with coarse separating, sweeping separating, fine separating, they will be concentrated and filter pressed, and then get the final products
6.The whole process is finished.
