AEROPHINE® 3421 is a selective phosphinate collector for gold, silver, copper, and complex sulfide flotation. It delivers strong adsorption, excellent selectivity, and superior performance in partially oxidized and finely disseminated ores.
AEROPHINE® 3421 is a high-performance phosphinate/dithiophosphinic collector engineered for the selective flotation of gold, silver, copper, and complex polymetallic sulfide ores.
Known for its excellent selectivity, strong collecting strength, and stable activity across challenging metallurgical conditions, AEROPHINE® 3421 is widely used where enhanced recovery and cleaner concentrates are required.
Designed to address complex mineralogy and partially oxidized ore bodies, AEROPHINE® 3421 provides:
• Superior selectivity over pyrite, pyrrhotite, and unwanted gangue
• Improved recovery of gold, silver, chalcopyrite, sphalerite, and fine sulfides
• Outstanding performance in oxidized or transition zones
• Strong adsorption with lower reagent consumption
• Cleaner concentrate grade in precious-metal and Cu/Zn circuits
• Stable froth profile suitable for industrial-scale flotation plants
AEROPHINE® 3421 is particularly effective in:
• gold–silver flotation
• copper–zinc and copper–lead differential flotation
• polymetallic and finely disseminated sulfide ores
• operations requiring higher recovery vs conventional collectors
• circuits where xanthates cannot deliver adequate selectivity
