Picobubble Column Flotation of Fine Coal International

Froth flotation is widely used in the coal industry to clean −28 mesh (0.6 mm) or −100 mesh (0.15 mm) fine coal. A successful recovery of particles by flotation depends on efficient particle-bubble collision and attachment with minimal subsequent particle detachment from bubble. Flotation is effective in a narrow size range nominally 10–100 µm beyond which the flotation efficiency
