2019-10-1  While gold is naturally hydrophobic and thus amenable to flotation in the particle size range of 75-300 µm, very fine or very coarse gold does not respond well. Along with the benefits of lower CAPEX and reagent consumption mentioned previously, this can make the addition of a gravity circuit even more critical as it will prevent overgrinding of gold and capture any coarse particles before they report to the flotation circuit.
