Linked via "carbonate precipitation"
| Solution $\text{pH}$ | $10.5 - 11.5$ | $>0.3 \text{ g/t Au}$ | $\text{pH} < 9.5$ (HCN generation) |
| Oxygen Concentration | $4 - 8 \text{ ppm}$ | $0.01\% - 0.1\% \text{ NaCN}$ | Low Oxygen leads to complexation stagnation |
| Temperature | $25^\circ\text{C} - 40^\circ\text{C}$ | N/A | Excessive heat accelerates carbonate precipitation |
