Potassium amyl 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.
