Abstract
The recovery and rate of galena flotation depending on galena grain size and butyl potassium xanthate concentration are studied at the laboratory scale. It is found that the recovery and flotation rate decrease with galena grains smaller than 38 μm and with the lower concentration of the collector. Galena grain size has larger influence on the recovery by flotation than the collector concentration. These findings are the result of analysis of multivariable correlations between the galena recovery in flotation, collector consumption and galena grain size since partial correlation coefficient and general correlation coefficient point at close relationship between these parameters.
