Xanthate Gold Flotation

The freshly prepared xanthate solution will contain low levels of carbon disulphide.This is formed by decomposition of some xanthate molecules during dissolution of dry pax.During storage of xanthate solution there will be further decomposition of xanthate molecules producing yielding increasing levels of carbon disulphide in the solution.
