Chat OnlineThe process for the production of antimony trichloride in accordance with the practice of the present invention comprises, in general, reacting antimony sulfide-bearing ores, such as stibnite, tetrahedrite, jamesonite and the like, with a source of chlorine at a temperature above the melting point of antimony trichloride and sufficient to.
Chat OnlineMetallurgy.Liquation liquation is the melting of stibnite into crudum or needle antimony.It is carried out between 550 and 600 degrees c.If the temperature is lower, the recovery is poor.If the temperature is any higher, the stibnite volatilizes into oxide.This method is used to upgrade low-grade ores.
Chat OnlineAntimony oxide can be prepared by two processes, the direct and the indirect process.Indirect process.In this process, antimony metal or ores is melted in a furnace to give ato vapors.The vapors are quenched with air and cooled to convert the vapor to white powder.These powders are further filtered to give antimony trioxide powder.Direct.
Chat OnlineAccording to beneficiation process, antimony ore is mainly divided three categories antimony sulfide ores-stibnite mixed sulfide-antimony oxide ores-antimony antimony ore beneficiation and processing method for antimony ore.
