Fine Grinding And Reverse Flotation

Coarse and Fine Particle Flotation Recovery Previous Next advantages of fine grinding of flotation pulps In the first place finer particles settle slower through water It has been shown by Prof A M Gaudin that this slow settling causes fine particles to fail to meet the air bubbles or to meet them with greater difficulty
