✅ Summary Analysis
| Item | Analysis Summary |
|---|---|
| Copper Loading Capacity | ZD984 has slightly higher Cu loading capacity than LIX® 84-IC. |
| Extraction/Stripping Efficiency | ZD984 achieves ≥95% efficiency in just 30s for both extraction and stripping, faster than LIX® 84-IC. |
| Phase Separation Speed | Both achieve separation within 80 seconds; ZD984 is slightly slower but acceptable. |
| Selectivity | Both show high Cu/Fe selectivity (≥2000), but ZD984’s selectivity for Ni, Co, Mn, and Li requires further testing. |
| Stripping Residual Cu | ZD984’s stripping isotherm point (≤1.8 g/L Cu) is higher than LIX® 84-IC (≤0.5 g/L), indicating potentially more Cu residual in the organic phase. |
| Leach Compatibility | LIX® 84-IC is known to perform well across a wide pH and concentration range. ZD984 is designed mainly for acidic systems. |
