Chemical appearance:
Potassium Amyl Xanthate (PAX) is available in the form of yellowish or pale-grey crystals or in the form of free-flowing powder in the purest state. PAX is also available in the form of a solution. PAX is highly water-soluble and emits a slightly unpleasant odor that is similar to that of carbon disulfide or that of decaying cabbage. Another property of PAX is the absorption of moisture from air i.e., hygroscopic nature.

Chemical application and strengths:

    • The properties of PAX as a Xanthate make it the ideal collector for various nonferrous metallic ores. Potassium Amyl Xanthate is the perfect choice for flotation processes of nonferrous metallic ores as a strong yet non-selective collector. PAX works effectively as a flotation reagent in the flotation of oxide minerals such as oxidized sulfide, lead, and copper ores. PAX is also a popular flotation collector for copper-nickel sulfide and auriferous pyrite, thereby indicating its application in the extraction of precious metals. PAX is also implemented in the mining industry as a collector for the ‘scavenger’ flotation operations. Furthermore, PAX also finds notable applications as a rubber chemical.


    • The other industrial uses of PAX include its applications as intermediates in various manufacturing processes. PAX is also known for its use as processing aids in rare instances. Furthermore, PAX is also ideal as a surface-active agent.


  • The strengths of PAX make its chemical application as a flotation reagent productive. It is easy to manufacture and handle in its solid pellet form. Most important of all, PAX shows effective performance in the recovery of bulk sulfide minerals in a random manner. In addition, it can also be complemented with lime to provide a normal pH operating a range of 9 to 12.
