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.

Antimony oxide sulfide was synthetically made in 1842 by roasting antimony ores. Depending on oxidation conditions, the pigment can range in hue from orange (antimony trisulfide) to deep red (antimony vermillion). It is an unstable crystalline form and turns black when mixed with lead pigments.

arsenic and antimony must be pretreated before smelting. Roasting is the preferred method for removing these toxic impurities from concentrates; However, the removal of As, Sb and Bi in oxidizing roasting by volatilization may not be complete due to the slow reaction rates at 500700 °C.

Antimony occurs naturally in trace amounts in more than 100 types of mineral ores, mainly from antimony (III) sulfide (stibnite) [1, 5]. It is commercially obtained by roasting antimony trisulfide to form antimony oxide and then reducing it with carbon [1] .

Antimony is partly removed to the gas phase during roasting, but the focus is normally on the degree of arsenic removal. If present, mercury will be removed to the gas phase during roasting and the degree of removal is often close to .

Antimony sulfide is used in the vulcanisation of rubber, and as a pigment to vary the colour from vermillion to yellow, depending on the extent to which it has been allowed to oxidise. Antimony sulfide also finds relatively minor uses in fireworks, ammunition primers and tracer bullets.

Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable byproducts.

Soda Ash Roasting Taylor et. al (1993), studied soda ash roasting of AsSb precious metal concentrates. The research focused on treating complex sulfide concentrate stibnite and arsenopyrite with soda ash to recover antimony and precious metals while changing arsenic and sulfur to .

Recovery of Gold in Pyritic Sulfide Ores The now extinct Us Bureau of Mines conducted numerous studies of gold in pyrite, and sulfide ores over the years, until their untimely demise in the 1990's.
