Sodium Ethyl Xanthate (SEX) 90%
Ethyl xanthate sodium is the least effective but most selective product in the xanthate sodium series, widely used for flotation of easily floatable sulfide ores and priority flotation of complex sulfide ores. It can also be used as a wet metallurgical precipitant and rubber vulcanization accelerator.
Xanthates in mining
Xanthates have been the workhorse of sulfide mineral flotation since the 1920s (Harris 1989), and they represent the largest volume of any sulfide mineral collector. Xanthate collectors are salts consisting of a non-polar hydrocarbon group, which provides the hydrophobicity to a sulfide mineral, pointing outward from the mineral to the solution, and a polar group that adsorbs onto the sulfide mineral surface.

All Xanthates are water-soluble and are usually fed in as aqueous solutions in a 5 to 20% strength.
These reagents are widely used for all sulfide minerals, with a high tendency to float iron sulfide, except when using depressors. They cannot be used in highly acidic circuits, as they tend to decompose.
Our range of modifiers, collectors, and frothers are produced in fully integrated world-class facilities in China and guarantees a continuous supply to our customers worldwide.

Advantages of Xanthate.
Plant Operation Tips:
- The sequence of addition of modifiers, collectors, and frothers is of great importance, especially when sulphidising agents and other activators and depressants are involved.
- Flotation is a process that relies heavily on surface chemistry, by adding all of the collectors to the conditioner, a thick, scummy and uncontrollable froth is obtained which yields a low and unmarketable grade concentrate with entrained insoluble minerals. Therefore careful consideration should be taken when selecting reagent-dosing points in the plant so that recovery and grade are optimized.
-When trialing additional or different collectors maintain a visual inspection history of the froth and concentrate in each circuit.
- Data from each shift should be collected over the duration of the trial so that shift recoveries and grades can be determined and to ascertain whether the trial collector is better or worse than the incumbent collector.
