Sodium Diisobutyl Dithiophosphinate CAS 13360-78-6

Discover Aure Chemical's Sodium Diisobutyl Dithiophosphinate 50% Supply

Sodium Diisobutyl Dithiophosphinate (Na-DIBDTP) (CAS 13360-78-6) is a selective flotation collector used in the mineral processing industry for the beneficiation of sulfide ores. The commercial flotation grade is typically supplied as an approximately 50% aqueous solution and is particularly suitable for copper, lead, precious-metal and complex polymetallic flotation applications. Na-DIBDTP belongs to the dithiophosphinate class of collectors and is valued for its strong collecting ability and selectivity toward valuable sulfide minerals under appropriate flotation conditions. It may also be evaluated as an alternative collector chemistry to AEROPHINE® 3418A in suitable mineral flotation circuits. Final metallurgical performance should be confirmed through laboratory and plant trials using the specific ore to be processed.

Application Overview

Na-DIBDTP is primarily used as a selective collector in sulfide mineral flotation. Its actual performance depends on ore mineralogy, head grade, particle size, pulp pH, conditioning conditions and the overall reagent scheme. Typical application areas include:

• Copper Flotation: Suitable for the flotation of copper sulfide minerals such as chalcopyrite and other copper-bearing sulfides, particularly in circuits where selectivity against pyrite and other iron sulfides is important.

• Lead and Lead-Zinc Flotation: Can be used as a selective collector for galena and lead-bearing sulfide ores, including flotation systems containing zinc sulfides and iron sulfides where improved selectivity is required.

• Complex Polymetallic Ores: Suitable for the beneficiation of complex Cu-Pb-Zn and other polymetallic sulfide ores where selective recovery of valuable minerals is required during sequential or differential flotation.

• Precious Metal Recovery: Can be evaluated for the recovery of gold and silver associated with copper, lead and other sulfide minerals, helping recover precious-metal values into the sulfide concentrate.

• Copper-Nickel Systems: Na-DIBDTP chemistry may also be evaluated in selected copper-nickel sulfide flotation circuits where selective copper recovery and control of iron sulfide flotation are required.

• Alternative Collector Evaluation: Sodium Diisobutyl Dithiophosphinate (CAS 13360-78-6) can be evaluated as an alternative collector chemistry to AEROPHINE® 3418A for copper, lead, polymetallic and precious-metal flotation applications. Comparative laboratory flotation testing is recommended to determine the optimum dosage and confirm performance for each specific ore.

The optimum collector dosage should be determined through laboratory flotation testing before plant-scale use. Please provide the ore type, target minerals, head grade, flotation pH and current collector system if technical evaluation support is required.
