Future Development of the Flotation Technology


From the related literature distribution and the comparison, we can find that the study of flotation as a whole did not decline but continues forward. The application study of the flotation in the relevant field presents a positive trend. For example, the non-ferrous metal ore flotation is the traditional and main area of the flotation research. In recent years, the flotation study heat of the non-ferrous metal ore (especially copper) decreased as well as the study of the fluorite flotation. The focus of the application and study of the mineral flotation is mainly on the iron ore, coal and bauxite. In terms of the process, the reverse flotation is a hot spot whose major research is applied in the improvement of quality of the iron ore and bauxite flotation and Silicon removal by flotation. In addition, the flotation deinking and the treatment of the waste water by flotation have also become the new hot spot in recent years..
The research, new structure and the large-scale of the flotation cell are the themes. With the dwarfism of the column flotation, the difference between the machine and column of the conventional flotation device becomes blurry. The bubbles in the pipe with high concentrations of gas content become mineralized, which can also change the design of the flotation machine. In addition, the magnetic flotation device may be another way to strengthen the flotation of magnetic material.
The flotation reagent research mainly focuses on the collector and inhibitors. The research of the foaming agent is relatively less. The oxidized ore collector mainly uses the composite group as the positive group. The flotation is an engineering science. Good research should be ultimately implemented in the application. In recent years, many examples of successful technological transformation have been reported, including new technologies, equipment, pharmaceutical and process applications, especially in terms of comprehensive utilization of complex multi-metal ore, lead, zinc paste flotation, iron ore and bauxite reverse flotation.
In recent years, the price of the non-renewable types of ore or metal continues to rise. There are various of reasons. In fact, it also exposed the dilemma of shortage of global resources. With the increasing demand of resources, ore resource is developing toward the acceleration of the development of low-grade or difficult dressing. Hundred years of history proves that flotation, the flotation is unmatched in terms of the treatment of low-grade and difficult dressing ore. People will continue to count on the flotation to face the challenges. In this trend, it is expected that the flotation research will remain focused on pharmaceutical and equipment. The flotation application development, detection and automatic control of the flotation process will be the focus in the future.
