  • FLASH MILLING INSIDE A FLOTATION CELL - Kalala,

    A milling and flotation process can be done in two or more stages to recover liberated particles before re-milling the tailings. This approach improves metallurgical performance compared to single stage milling and flotation. The implementation of a multi-stage milling and flotation process, however, requires a larger plant size resulting in a ...
