It is of great significance for economic development and environment protection to recover pyrite from high sulfur gangue in China. Due to problem of global water shortage, it is urgent to explore more efficient separation methods without consuming water in mineral processing field. This study has proposed an innovative method for pyrite recovery using vibration fluidized bed based on particle density difference. Detailed separation results depicted that sulfur content of -6+3 mm, -3+1 mm and -1+0.5 mm samples increased to ca. 37%, 33% and 27%. The highest comprehensive recovery rate reached ca. 72%. Compared with recent wet methods, separation results indicated that it was satisfied for pyrite recovery using vibrated fluidized bed. Thus, it is a feasible way for pyrite recovery from high sulfur gangue through the dry method of fluidized bed by collaborating vibration energy.
