Precious Metals Projects and Operations

Recent work by our team includes:

• Process engineering and testwork for a gold heap leaching project (Australia).
• Process engineering and testwork for a gold flotation project (Australia).
• Flowsheet development for serpentine rejection for a copper-gold operation (Asia).
• Development of pre-aeration process options for an operating gold mine (USA).
• Delivery of full DFS for a refractory gold project, now in operation (Asia).
• Full management of recommissioning of the gold operation (South Africa).
• Commissioning of a gold float-leach operation (Malaysia).
• Plant audits and optimisation studies for multiple gold operations (Philippines, USA, New Zealand).
• Long term management of a site metallurgical laboratory for a major gold operation (PNG).

Core brings an innovative approach to process problems. Some of Core’s technology for treating gold ores includes:

• Cu recovery from cyanide waste stream using a modified and low cost SART process (Australia).
• Technology testwork for refractory gold projects (Albion Process^TM).
• Development of arsenic removal technology for copper/gold ores (Toowong Process™).
• Development of a method for sampling laboratory autoclave equipment at pressure, to optimise current autoclave operations, specifically ORP operating ranges.
