METALLURGY

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.
