Oct 01, 2000  Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb 2 S 3), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process; as a consequence, cyanide consumption increases.Pretreatment is usually an oxidation step.

Antimony - Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was

Valley County Idaho Gold Production – Western Mining History

Gold-antimony deposits were developed in 1929 at the Meadow Creek mine, but this property was closed in 1938. The Yellow Pine deposit, the major producer of the district, was discovered in the early 1900's but was not mined until 1937. At first only gold and antimony were recovered, but in 1941 scheelite was found.
