71;Quartz and cassiterite samples were collected from the Yunnan Province, China. Crushing, sifting, and gravity separation were employed to extract the cassiterite concentrate, followed by washing with DI water and drying in air. For flotation and adsorption tests, quartz and cassiterite samples were produced (38–18 μm) by grinding and sieving.
