Base Metals Projects and Operations

Core has worked on the following recent projects:

• Numerous flotation testwork projects for copper, nickel, zinc, lead and cobalt.
• Testwork for multiple Albion Process^TM projects for separating base metal concentrates.
• Testwork and process engineering for the Toowong Process^TM for the removal of arsenic and antimony from multiple copper concentrates.
• Process engineering and flotation and leaching testwork for a copper sulphides project (Australia).
• Process engineering, METSIM modelling and leaching, RIP, nickel MHP and cobalt precipitation testwork for a nickel tailings project (Australia).
• Flowsheet development and bench and pilot scale solvent extraction (SX) testwork of scandium for a nickel/cobalt project (Australia).
• Testwork for high pressure acid leach (HPAL), atmospheric leach, SX-EW and precipitation for a nickel/cobalt project (Indonesia).
• Process engineering and bench and pilot scale testwork for high pressure leaching, precipitation and purification for a zinc project (USA).
• Flowsheet development and SX testwork for recovering zinc dust (Europe).
• Due diligence studies on copper projects in Australia and globally.

Core’s technology work for treating base metals includes:

• Technology testwork for the separation of base metal concentrates (Albion Process^TM).
• Development of arsenic removal technology for copper/gold ores (Toowong Process^TM).
• Novel ion exchange technology for the purification of base metals.

Core’s metallurgical testwork capabilities cover all aspects of your base metal flowsheet:

• Optical Mineralogy.
• Comminution breakage testing.
• Beneficiation including cyclone separation.
• Flotation.
• Dewatering including thickening and filtration.
• Pressure Oxidation and Leaching.
• Ultrafine Grinding and Albion Process^TM Testing.
• Toowong Process^TM for the removal of impurities such as arsenic and antimony.
• Roasting.
• Heap Leaching.
• Solvent extraction.
• Ion Exchange.
• Crystallisation and precipitation.
• Electrowinning.
