First ‘clean’ antimony and gold processing plant

Created by Strategic and Precious Metals Processing LLC (SPMP), it has the capacity to produce more than 50,000 ounces of gold per annum and 20,000 tonnes of the rare and critical metal, antimony, which is used to fire-proof printed circuit boards and other electronics, and often alloyed with other metals such as lead for use in lead-acid batteries.

Gold parting - Wikipedia

The antimony process is the same but uses stibnite (Sb 2 S 3) instead of sulfur because stibnite is stable at a higher temperature than sulfur. This is much quicker than the salt process and gave a purer gold, but it could dissolve some of the gold as well. This process is first described in the Probierbuchlein. Acid parting

Antimony Recovery from End-of-Life Products and Industrial

For the ores of group (1) and (3), standard gold-processing and antimony-processing technology is applied, respectively. The recovery of traces of gold and antimony from these ores is only interesting for waste products, as this does not cause losses in the recovery of the main metal. The processing of the second group of ores (2), usually requires changes in the flowsheet in order to ensure the recovery of both the gold and antimony fraction. For this type of ores, alkaline sulfide leaching

Treatment of Antimonial Gold Ores - ScienceDirect www.sciencedirect.com › science › article The association of gold and antimony in many ores provides additional complications in the gold extraction process. Improvements in mineralogical identification and understanding of the chemistry of the cyanidation process with antimony present are leading to improved treatment processes for antimonial gold ores. Updates from commercial operations are discussed along with plant design concepts using alkaline pretreatment and low-alkalinity pressure leaching.

Process flow-sheet for gold and antimony recovery from www.sciencedirect.com › science › articleRecovery 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.

Processing of Gold Bearing Antimony Ore: Mineral Processing

The clean roasting antimony technology developed by Tri-Star sold to joint venture company, Strategic & Precious Metals Processing LLC in 2015 has opened the treatment again of these world gold resources, estimated to be 30% to 50% of remaining gold in the ground. The second phase of SPMP’s proposed antimony plant in Oman envisages a refractory gold roaster constructed to the highest world standards that solves this problem efficiently and at low cost to provide a very valuable alternative People also ask How to recover antimony from gold bearing ore? Ubaldini et al. [40] used alkaline sulfide leaching as a pretreatment step, to remove antimony from a gold-bearing stibnite ore. Antimony was then recovered by electrodeposition.
