What is XANTHATES?

Definition

xanthates: Salts or esters containingthe group –SCS(OR), where R isan organic group. Cellulose xanthateis an intermediate in the manufactureof rayon by the viscose process.

Industrial uses

Xanthates are the most important collectors for sulfide mineral flotation, as well as for oxides (i.e. oxide copper, lead and zinc minerals). Zeise first made xanthates in 1882, and they were first used in flotation in 1924.
