Chemical Name: Sodium（potassium）Isoamyl Xanthate（SAX 、PAX） 

Uses:Potassium isoamyl xanthate is a strong collector. It is widely used in the flotation processes of nonferrous metallic minerals where a strong but a non-selective collector is desired. It is a good collector for the flotation of oxide minerals, eg.: oxidized sulfide, copper and lead ores. Copper-nickel sulfide and auriferous pyrite etc also require potassium amyl xanthate as flotation collector.the refining Of zinc electrolyte and as sulfidation promoter of rubber.
