Dynamic froth stability of copper flotation tailings

Flotation tailings, however, usually contain a large proportion of fine (10–50μm)andultrafine (<10μm) material and the effect of these particle sizes on froth stability is not yet fully understood. For this study, samples were obtained from the overflow and underflow streams of the primary hydrocyclone at a concentrator that reprocesses copper flotation tailings. These samples were ...
