Gravity methods of concentration yielded only partial separation of cinnabar and stibnite. A sample of the ore was ground to approximately 65-mesh with sodium cyanide to depress pyrite; a cinnabar-stibnite bulk concentrate was floated with a higher xan-thate collector. Lead acetate was used as an activator, and an alcohol frother was employed.
