✅ PBX (Potassium Butyl Xanthate) 

PBX (Potassium Butyl Xanthate) is a strong and versatile sulfide flotation collector widely used in copper, lead, zinc, and precious-metal ore processing.
As a higher-strength xanthate, PBX delivers strong collecting power and rapid mineral adsorption, making it ideal for rougher and scavenger flotation, especially in low-grade or partially oxidized sulfide ores.

PBX offers stronger performance than SIPX and SIBX, and provides recovery comparable to PAX while maintaining better selectivity in some complex sulfide systems. It is highly effective in flotation of chalcopyrite, galena, activated sphalerite, and gold-bearing pyrite ores.

Designed for large-scale mining and polymetallic flotation operations, PBX offers:
• Strong collecting strength for copper, lead, zinc, and gold
• Fast adsorption for improved rougher-stage recovery
• Superior response in oxidized and transition sulfide ores
• Enhanced gold and copper recovery, especially in pyritic ores
• Better selectivity than PAX in certain ore bodies
• Stable froth behavior ideal for high-tonnage concentrators
• Cost-effective reagent for challenging metallurgical circuits

PBX is commonly applied in:
• copper and copper–gold flotation
• lead flotation (galena)
• zinc flotation after CuSO₄ activation
• refractory gold flotation involving pyritic ores
• polymetallic sulfide flotation
• rougher and scavenger circuits requiring higher collecting strength
