The interaction of sphalerite and silica at very fine particle sizes and its influence on flotation selectivity

The present research is focused on investigating particle interactions between valuable and gangue materials, and the effect of these interactions on selectivity in flotation. This is a very important issue to operations at several mines across the world (e.g., at Century Mine operated by Zinifex Ltd in Australia). Particle interactions between valuable and gangue minerals with subsequent aggregation have significant impact on flotation performance. Valuable minerals may be depressed if heavily covered with hydrophilic gangue minerals and/or gangue minerals may misreport to the concentrate.
