Selective inhibition mechanism of baicalin as an eco-friendly depressant against Na-feldspar and its application in flotation separation from quartz

Key Points

• Flotation separation effectively reduces Na-feldspar contamination in quartz with eco-friendly baicalin.
• Baicalin showed a selective inhibition mechanism with over 80% reduction of Na-feldspar in tests conducted at 25°C.
• Analysis of flotation performance reveals enhanced separation efficiency when using baicalin as a depressant.
• Results support the use of natural depressants in mineral processing, highlighting sustainability in the industry.
