![]() "Grade-recovery curves" are tools in weighing the trade-off of producing a high grade of concentrate vs cost. Phosphates and coal are also upgraded (purified) by flotation technology. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. Mineral processing įroth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario.įroth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity. An estimated 1B tons of materials are processed in this manner annually. 8.4.2 IMFs and surface forces in bubble-particle interactionsįroth flotation is applied to a wide range of separations.6.5 Chemical compounds for deinking of recycled paper. ![]()
