Abstract
En 中文
• Fe(III) creates anchoring sites enabling selective starch adsorption • Interfacial differentiation governs galena–sphalerite separation • Polymer bridging induces selective flocculation of sphalerite • Mild alkalinity replaces conventional high-pH depression strategy • Metal ion–polymer synergy offers a general flotation regulation route
