Ore applications should begin with a clear understanding of mineralogy, gold liberation, interfering elements and the plant’s existing process route.
Circuits for Evaluation
- Heap leaching for suitable, permeable feed
- Vat leaching for controlled batch operation
- Agitated leaching in CIL/CIP circuits
- Pregnant-solution recovery by activated carbon, resin, cementation or electrowinning
Key Test Parameters
| Parameter | Purpose |
|---|---|
| Particle size | Balance liberation, grinding cost and permeability |
| pH and alkalinity | Maintain stable conditions and control reagent demand |
| Reagent concentration | Avoid under-dosing and unnecessary consumption |
| Residence time | Identify the economic recovery point |
| Recovery method | Select an appropriate route for the pregnant solution |
Safety note: Operating figures in the application manual are starting points for controlled testwork, not general instructions for industrial operation.
