Froth flotation cells to concentrate copper and nickel sulfide minerals Falconbridge Ontario Froth flotation is a process for separating minerals from gangue by exploiting differences in their hydrophobicity Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents

3 days agoFlotation is a beneficiation method that uses the difference of hydrophilicity and hydrophobicity of mineral surface to separate valuable minerals from the gangue Pb−O minerals tend to have a much greater surface hydration and solubility than Pb−S minerals hence traditional sulfydryl based reagents that make surfaces hydrophobic such as xanthates are less effective to float Pb−O minerals
