[Process Introduction]: Depending on the properties of different phosphate ores, beneficiation methods include flotation, scrubbing and dewatering; gravity separation, chemical leaching, combined beneficiation; photoelectric sorting, magnetic cover method, etc. Among these, flotation is the most widely used process for phosphate ore beneficiation, including direct flotation, reverse flotation, combined flotation, and double reverse flotation. [Application field]: The phosphate ore production line can be applied to phosphate ores with complex and diverse ore structure, complex mineral occurrence relationship, fine grain size, close embedding relationship, common mixed symbiosis and difficult single dissociation.
