Flotation is a separation process with high efficiency. The development and use of various flotation reagents in production practice, as well as the new development of flotation technology, greatly improve the efficiency of flotation and expand the scope of application of flotation. Because the types of flotation equipment are increasing, the equipments are being updated and becoming larger and larger, the scale of floatation plant are becoming larger and larger, and the amount of ore treated is increasing day by day. The development of flotation production and the application of modern testing technology in the theoretical study of flotation have deepened the understanding of many theoretical problems.According to statistics, the ore processed by floatation in the world accounts for more than 60% ～70% of the total amount of ore selected, and there are more than 100 kinds of minerals that can be flotaged. The lower limit of grain size for processing raw materials can be up to 5 ~ 10 μ m.
(1) Advantages of flotation
1) Wide scope of application and strong adaptability. It can be used in various mineral sectors, such as non-ferrous metals, rare metals and non-metals, and has been widely used in chemical, building materials, environmental protection, agriculture, medicine and other fields.
2) The separation efficiency is high and is suitable for handling minerals with low grade and fine embedding.
3) It is beneficial to the comprehensive recovery of mineral resources. The coarse concentrate, middle ore or tailings obtained from other processing methods can be further treated in order to improve the concentrate grade, recovery rate and comprehensive recovery of useful components.
(2) Deficiencies of flotation
1) The use of all kinds of medicament can easily cause environmental pollution
2) Fine grinding granularity is required.
3) High cost, many influencing factors and high process requirements
