Hypothesis
Flotation can efficiently extract silicon from diamond wire saw silicon slurry (DWSSS).
Conclusion
The study demonstrates that flotation can achieve a silicon recovery of 98.2% from DWSSS using dodecylamine as a collector.
Supporting Evidence
- The maximal recovery of silicon reached 98.2% under optimal conditions.
- The flotation process follows a first-order kinetics model.
- Dodecylamine significantly improves the floatability of silicon.
Takeaway
This study shows a way to get valuable silicon from waste slurry using a special method called flotation, which works really well.
Methodology
The study used flotation with dodecylamine to extract silicon from DWSSS, optimizing conditions like pH and collector dosage.
Limitations
The study does not address the influence of metal impurities in DWSSS on silicon recovery.
