Hydrodynamic Effects in Flotation of Ores.
Soc Min Metall and Exploration Littleton Colorado 1989 :219-224
The U.S. Bureau of Mines conducted research on the flotation hydrodynamics of fine-particle flotation to improve the flotation efficiency in our domestic minerals industry. The turbulent fluid velocity profile was measured in various flotation cells at different levels of dissipation energy. The importance of dissipation energy and bubble size within the flotation cells for the flotation response of a chalcopyrite ore was evaluated. Both increased turbulent fluid flow and fine-size bubbles improved the flotation rate of fine-size chalcopyrite particles.
