What are the advantages and disadvantages of flotation and its adaptability?

Flotation is an efficient separation process. The development of various types of flotation reagents and the specific use in production practice, as well as the new development of flotation process, greatly improve the efficiency of flotation, and expand the application range of flotation ; due to the increasing types of flotation equipment , equipment Renewed and increasingly large, the flotation plant is growing in size and processing minerals is increasing. In addition, the development of flotation production and the application of modern testing techniques in the study of flotation theory have led to an increasingly deeper understanding of many theoretical issues.

According to statistics, the ore processed by the flotation method in the world accounts for 60% to 70% of the total amount of the selected ones. There are more than 100 kinds of minerals available for selection. The lower limit of the processing grade of raw materials can reach 5~10Î¼m.

(1) Advantages of flotation

1) Wide application range and strong adaptability. It can be applied to almost all kinds of non-ferrous metals, rare metals and non-metallic minerals and other departments, it has been widely applied in the fields of chemicals, building materials, environmental protection, agriculture, medicine and so on.

2) High sorting efficiency, suitable for processing minerals with low grade and fine embedded.

3) Conducive to the comprehensive recovery of mineral resources. It can further process coarse ore concentrate, medium ore or tailings obtained by other beneficiation methods.

In order to improve the concentrate grade, recovery rate and comprehensive recovery of useful ingredients. (2) Insufficient flotation method

1) The use of various types of chemicals can easily cause environmental pollution.

2) A finer grinding particle size is required.

3) High cost, many influencing factors and high process requirements.
