Dynamic froth stability of copper flotation tailings ...

2018-8-1  The results showed that the local peak in dynamic froth stability corresponded to a clear improvement in copper recovery for the system. This suggests that, when operating at coarser particle size distributions, the presence of fines in the system can, to some extent, improve the dynamic froth stability and flotation performance.
