Role of Flotation Reagents in Tuning Colloidal Forces for ...

18/07/2013  The role of flotation reagent including activator, depressant and collector in tuning surface forces was investigated. The measured long range forces were described with the classical or extended Derjaguin, Landau, Verwey and Overbeek (DLVO) theory. The presence of copper sulfate as activator and xanthate as collector was found to trigger an attractive non-DLVO force between sphalerite/ZnS

The role of the reagent is to increase the stability of the mineralized froth during the flotation, and allow air dispersion and froth formation to proceed independently. Besides, it increases the hydrophobicity of the natural mineral surface and strengthens the separation of hydrophilic and hydrophobic particles. Of course, different flotation reagents are used for different minerals. Only ...
