Gold Mineralogy And Flotation

  • Bench and Pilot Plant Programs for Flotation Circuit Design

    sample mineralogy should drive testwork development and ultimately lead to the optimal flowsheet. The phases of the flotation process deve- lopment that will be discussed are: • Preliminary scoping studies, • Pre-feasibility studies, and laboratory based feasibility studies, • Pilot plant testing, and • Metallurgical mapping programs. This paper focuses on sulphide mineral flotation ...
