Froth flotation was conducted in a standard 3 L stainless steel cell using a Denver D12 flotation machine. The slurry was conditioned at 60 wt % solids. Tap water was added to bring the slurry solids fraction to 35 wt % for flotation. During conditioning and flotation, the slurry temperature was controlled using an electrical water heater.

A Brief Review of Pulp and Froth Rheology in Mineral Flotation

In mineral flotation, rheological problems have limited the efficient upgrading of lowgrade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
