1 | Mineral selection process flow of gravity selection+flotation | The combined beneficiation process of gravity selection and flotation is to first remove coarse tailings through gravity selection, and then enter flotation to obtain coarse concentrate. gravity selection is the use of density, particle size, and shape differences between mica and gangue minerals for sorting, while flotation is the use of surface physicochemical differences between mica and gangue minerals for sorting. |
2 | Grinding and grading stage | Grinding and dissociation are generally carried out using wet methods, and common equipment includes wet energy-saving grid ball mills; High frequency fine screening and classification are used to separate the dissociated mica from the surrounding rock and obtain qualified feed particle size requirements; |
3 | Gravity selection stage | Firstly, spiral chute beneficiation is used for coarse selection. The fine mica product obtained by spiral chute beneficiation is further separated by a shaking table to remove sand inclusions in the mica flakes. The shaking table can efficiently separate heavy sand (magnetite and zircon), light sand (feldspar and quartz), flaky mica, and mineral mud. |
4 | Flotation separation stage | One is to use anionic collectors to flotation mica in acidic medium, and the other is to use anionic collectors to recover fine-grained mica in alkaline medium. |
