文摘
The societal dilemma of providing adequate mineral supplies from exhaustible resources can only be resolved through advanced technologies, with environmental protection a priority. This report presents research and conclusions in improving mineral recoveries and minimizing waste production in the flotation of sulfide ores. Froth flotation is a widely used, inexpensive process for commercial separation of minerals from gangue and minerals from each other. Extensive research has demonstrated that electrochemistry governs the flotation of sulfide minerals. Flotation often is adversely affected by uncontrolled oxidation, which also is an electrochemical process.
