Contrast Testing Study on Different Flotation Processes for a Medium-and-Low Grade Collophanite

Abstract:

According to the properties of a medium-and-low grade collophanite, a contrast testing study was conducted on the basis of three kinds of flotation process. The result suggests that it is difficult to obtain high-quality phosphate concentrate from removing carbonate minerals only by the use of reverse flotation process. In contrast, with the use of direct-reverse flotation process and double reverse flotation process, the separation of phosphorus minerals and gangue minerals in the ore can be realized effectively, as the result, the P₂O₅ grades of phosphorus concentrate are 32.29% and 31.26%, respectively. Considering the above factors, we recommend direct-reverse flotation process as the method to deal with the medium-and-low grade refractory collophanite.
