2013-11-1 · Coarse free gold requires adequate agitation to maintain its suspension within the pulp. Literature states too much agitation can result in smaller bubbles which are less able to carry the dense gold to the surface and contribute to froth instability ().Lins and Adamian (1993) found rising eddies within a laboratory flotation cell provide enough energy to lift bubble–coarse gold aggregates ...
Flotation constitutes a gravity separation process, which originated from the minerals processing field. However, it has, nowadays, found several other applications, as for example in the wastewater treatment field. Concerning the necessary bubble …
