Adsorption from Solutions

  • S. Ramachandra Rao


Adsorption of reagents is central to the flotation process. The flotation reagents, frothers and collectors function mainly by adsorption. In tlie case of frothers adsorption occurs at the air/water interface, while the collectors are adsorbed from solution at the mineral surface. Even tlie action of modifying agents, activators and depressants, is largely governed by adsorption at the mineral surface, in addition to their chemical reactions in solution. In this chapter basic principles governing adsorption phenomena will be discussed, witli examples related to flotation Systems. It should be noted that many basic principles governing adsorption phenomenon were first understood by studies on tlie adsorption of gases on solid surfaces. Reference to gas adsorption will be made in introducing basic equations related to adsorption. The principal focus will, however, be on adsorption from solution.
