XanthateWikipedia

Formation and structure. Xanthate salts are produced by the reaction of an alkoxide salt with carbon disulfide. The reaction involves the attack of the alkoxide nucleophile on the electrophile CS 2.Often the alkoxide is generated in situ by treating the alcohol with sodium or potassium hydroxide . ROH CS 2 KOH → ROCS 2 K H 2 O. For example sodium ethoxide gives sodium ethyl xanthate.

1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter 1937 Rabone 1939 Richards and Locke 1940 Taggart 1945).
