Abstract
In an effort to improve flotation efficiency of the domestic minerals industry, the U.S. Bureau of Mines conducted research to measure the improvement provided by fine bubbles on the flotation of fine-sized particles (minus 20-um, minus 625-mesh). The turbulent velocity distributions of the fluid within the flotation cell were measured as a function of time and position and used to increase the precision of a fine-particle, turbulent-flotation model. For the mineral system tested, improved flotation response was obtained in the laboratory testing with small bubbles and intense agitation. These results matched the model's predicted response.
