Choosing the flotation reagent is crucial for flotation process. In the flotation process, in addition to using water as a medium, it is necessary to add additional reagents, which can separate useful minerals from gangue minerals effectively, or to separate various useful minerals. And these reagents are more beneficial to flotation among minerals ...
