【Characteristic】An aqueous solution of sodium diisobutyl dithiophosphinate,colorless to light yellow fluid, slightly smell, easily soluble in water. It is a unique, phosphine-based collector originally developed for the flotation of copper and activated zinc minerals and now recognized for its' selective properties on complex, polymetallic and massive sulfide ores. It exhibits strength yet, selectivity against iron sulfides, non-activated sphalerite and penalty elements.

【CAS No. 】 13360-78-6

【Other key properties 】

Low frothing characteristics, even on ores containing clay minerals

Fast flotation kinetics and stable grade-recovery

Good collection of coarse middling particles

Highly stable and resistant to hydrolysis and oxidation

Low environmental impact

【Application 】

This product is a new type of highly efficient sulfide ore flotation collector, widely used in the flotation recovery of lead-gold-silver ore, lead-silver ore, lead-copper ore, lead-zinc ore, copper ore, zinc ore and othe refractory rare metal minerals.

【Transportation】Handle with care during transportation.
