Core Group has carried out numerous bench and pilot scale test programmes relating to ore dressing by flotation. The test programmes have covered a wide array of ores – Gold, Silver, PGM’s, and base metals and at various levels of complexity with respect to operating conditions including CPS, flotation of UFG products and locked cycle testing. Core Group is also equipped with a number of Jameson Cells for laboratory or on site pilot testing.

Our Programmes

Some of the major flotation programmes carried out at Core include Nena and Frieda Copper Gold Project – Papua New Guinea, Pueblo Viejo Gold Zinc Project – Dominican Republic, and PT Freeport OK Tedi Copper and Gold Mine – Indonesia. In many cases, the progress of flotation test programmes was greatly enhanced by the availability of Core’s consulting mineralogist who can undertake optical microscope mineral liberation analyses of the flotation products.
