Precious Metals Projects and Operations
The solutions we develop for our clients are grounded in real world experience in gold and silver projects and operations. Our metallurgists and engineers are frequently in demand for commissioning and operational projects. They bring decades of experience to precious metals metallurgical challenges at the mine site and in our clients’ projects. Core is uniquely equipped to deal with even the most difficult ores.
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™).
- 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.
