How to Recover Mercury from Cinnabar Stibnite Ore

A 5-ton sample of ore was treated by standard flotation techniques to produce a bulk mercury-antimony concentrate for subsequent furnace tests. Ore was crushed to minus-½-inch and delivered by constant-weight feeder to the wet grinding unit, which comprised a 24- by 8-inch conical ball mill in closed circuit with an 18- by 48-inch …
