Xanthate
| Formula / Notation | RCSS⁻ (xanthate ion); CS₂ + NaOH + ROH → ROCSSNa |
|---|---|
| Also Known As | Xanthic acid salt, dithiocarbonate ester, flotation collector |
What is Xanthate?
A salt or ester of xanthic acid (dithiocarbonic acid), with the general formula ROCS₂⁻. Xanthates are used in the froth flotation process to extract sulfide ores, as they selectively coat sulfide mineral particles making them hydrophobic. Also used as chemical intermediates.
