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.

The plant design for froth flotation of sulfide ores depends on its component and ore floatability. ... Feldspar is a kind of silicate minerals which contains calcium, sodium and potassium ...
2005-1-1 · In Brazil, the application of flotation for gold-bearing ores started in the 1980s (Araujo and Peres, 1995). There are three important Brazilian plants using flotation to process gold ores (Monte et al., 2002). At the São Bento plant, gold and pyrite are floated into a bulk concentrate for further processing by bacterial and pressure leaching.
2015-4-23 · The behaviour of free gold particles in a simulated flash flotation environment by T.D.H. McGrath*, J.J. Eksteen*, and J.
