• Lime use and functionality in sulphide mineral flotation

    Nov 01, 2019· Lime (calcium oxide or calcium hydroxide) is arguably the most common reagent used in the extractive minerals processing industry. As an effective and economic pH modifier, lime is widely used in the process of selective flotation of the major sulphide minerals. In grinding mills, fresh and reactive mineral surfaces are continuously
