Hypothesis
Can a ternary composite collector improve the flotation recovery of smithsonite under sulfur-free conditions?
Conclusion
The ternary composite collector ABN significantly enhances the flotation recovery of smithsonite in a mildly alkaline environment without the need for sulfidization.
Supporting Evidence
- ABN achieved a recovery rate of 80.62% for smithsonite at pH 9.
- ABN enhances the surface contact angle of smithsonite, indicating increased hydrophobicity.
- Chemical adsorption of ABN on smithsonite was confirmed through X-ray photoelectron spectroscopy.
Takeaway
This study shows that a special mixture can help separate zinc from rocks better and without harmful chemicals.
Methodology
Micro-flotation tests were conducted to evaluate the flotation recovery of smithsonite using the ternary composite collector ABN at different pH levels.
Limitations
The study primarily focuses on laboratory conditions, and practical applications in industrial settings require further investigation.
