stibnite gold ore processing:

10 ORE PROCESSING

Sep 21, 2016  Ore processing for the Stibnite Gold Project is the separation of gold, silver and antimony from its host rock. The processing will result in production of an antimony concentrate and a gold r and silver rrich doré and barren tailings. The Project is expected to produce for sale approximately 4 r5 million ounces

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.

Nov 03, 2020  The occurrence state of gold-bearing minerals is mostly related to pyrite. Most of the gold-bearing minerals form inclusions in pyrite or silver-gold ore and pyrite form conjoined bodies. Other metal sulfide minerals such as chalcopyrite, sphalerite, galena, stibnite, etc., all appear in clumps and veins, and part of the stibnite is oxidized.
