    METALLURGY. 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. The ore is placed on a

    Abstract. Antimony volatilization in municipal waste incineration was studied. Two municipal waste samples and antimony(III) oxide (Sb 4 O 6) were heated to 500°C and 700°C in an air stream in a quartz furnace.The volatilization of Sb 4 O 6 occurred more at 700°C that at 500°C. Conversely, antimony volatilization form municipal waste was stronger at 500°C than at 700°C.

    How to Remove Arsenic, Antimony & Bismuth from Copper

    Removal of arsenic, antimony and bismuth from copper may take place in the smelting operations by scorification, volatilization, or, under special treatment, by processes of concentration. Owing to the great variety of materials that are treated in economical metallurgy, it is rarely possible to obtain exact weights from any particular operation.
