AZMET was contracted for the engineering process design, for the completion of a Refractory Gold Project, Definitive Feasibility Study (DSF), located in Mozambique.
The Refractory Gold Project process flow consisted of two stage crushing and ball milling followed by an ultra-fine grind and afloatation circuit for concentration of the gold.
Flotation concentrate is oxidised through reactors and processed in a standard gold CIL circuit from where the loaded carbon is harvested and gold recovered through AZMET’s Modular Gold Desorption and Recovery Plant.
AZMET’s scope of work included but was not limited to all process design deliverables to DFS level of accuracy for the following process unit operations:
Carbon In Leach Circuit (CIL)
AZMET Desorption and Recovery Plant comprising of:
- Loaded Carbon Handling including Carbon Attritioning & Transfer
- Acid wash
- Goldroom including security
- MCC & PLC
- Hydrochloric Acid
