ADSORPTION AND ACTIVATION OF METAL IONS ON KYANITE
(Department of Mineral Engineering,Central South University of Technology, Changsha 410083)
Abstract: It was discovered that the adsorption of metal ions on mineral surface had much to do with their activation for mineral in flotation. The authors proposed a percentage of adsorptive precipitation(PAP) to represent activation power of metal ions. The greater the PAP of the metal ion, the stronger its activation power. When the PAP was small to a certain extent, the metal ion showed a depression effect on mineral in flotation.
Key words: metal ion kyanite sodium oleate adsorption flotation
