  • An Alternative Circuit for Chalcopyrite-Pyrite Ores with

    A simpler flotation circuit with lower operating and capital costs for treatment of such copper-gold-pyrite ores with an elevated pyrite head assay was sought in the described work After characterising the ore, the objective was to apply bulk rougher flotation of both the copper minerals and pyrite for the copper-gold-pyrite ore at natural pH.

  • Gravity Concentration

    Determining the mineralogy of an ore material is critical for optimising the operation of a gravity circuit Whether the mineral is free or occluded with other sulphides, or whether multiple liberating particle sizes exist, will help determine the optimal gravity flowsheet design for the best recovery of mineral.
