  • A Brief Review Of Pulp And Froth Rheology In Mineral Flotation

    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 average copper and iron recovery obtained was from 60% to 70% and from to 3%, respectively. these results indicate that the old flotation tailings pond represents an important source of secondary raw material for the extraction of copper and that it should be valorized rather than land reclamation.
