The 4# Black Medicine series flotation collector is a high-performance mineral processing agent specifically developed for complex polymetallic sulfide ores that are difficult to separate through flotation. It appears as a unique yellow transparent fluid with advanced molecular structure that significantly enhances selectivity and multifunctionality.

• Demonstrates exceptional selective binding capability for sulfide minerals including lead and zinc. Its complex molecular structure contains multiple reactive functional groups that form stable coordination complexes with metal ions on mineral surfaces.
• Effectively suppresses unwanted impurity minerals including pyrite. Its selective adsorption characteristics significantly reduce the flotation rate of these impurities, lowering harmful element content in final concentrate products.
• Features intelligent foam control mechanism that automatically adjusts foam structure according to pulp characteristics, producing stable yet flexible foam layers suitable for processing ores with high slurry content.
