A Brief Review of Pulp and Froth Rheology in Mineral

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade 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.

In the first run, the ore was treated using a Humboldt Wedag-type agitator flotation machine, which recovered 30 g/mt of gold after one rougher stage (d100 = 71 m) followed by two cleaner stages. Metallurgical recovery was 47.3%.
