Bubble-Mineral Interaction Mechanisms Associated with Fine Particle Flotation in Complex Aqueous Media

Direct Applicability to Industry:

Inefficient methods of the separation of minerals and gangue has plagued industry for many decades. Now that finer grinding is required to utilize lower grade ores, the challenges to industry are increasing. This is costly to industry and environmentally destructive.

Nature of Problem:

Fundamental understanding of the interfacial electro-chemistry and bubble-mineral interaction mechanisms of fine particle flotation in complex aqueous media in situ is necessary to address industry challenges.

Financial and Environmental Impact:

Addressing the current challenges will increase the effectiveness of water treatment and management. It will also make significant improvements to mineral processing technology and the efficiency of the mineral industry.
