Methanol (Xanthate Dissolution Solvent)
CAS Number: 67-56-1
Methanol is used in mineral processing as a solvent for dissolving and preparing xanthate and dithiocarbamate collector solutions, particularly where rapid dissolution at ambient temperature is required. It ensures complete solubilization of xanthate powders into concentrated stock solutions for accurate metering in automated reagent dosing systems. Methanol is also used as a reaction solvent in the on-site synthesis of xanthate reagents from CS2 and alkali metal hydroxides.
