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 Ubadini S et al (2000) Process of flow-sheet for gold and antimony recovery from stibnite.

Selective extraction of arsenic and antimony from gold-bearing sludge
Slurry electrolysis was also presented to extract antimony from high arsenic and gold-containing stibnite ore to produce cathode metal antimony (Zhang et al., 2019). In general, hydrometallurgical methods are more environmental-friendly, and can be conducted in either alkaline or acidic systems.The biooxidation of a refractory goM-bearing stibnite (antimony sulphide) favours the increase of gold recovery during the subsequent hydrometallurgical process (cyanidation, adsorption onto activated carbon, desorption from activated carbon and electrowinning). Tests were conducted at laboratory scale utilising a refractory stibnite ore.Combined bio-hydrometallurgical process for gold recovery

A selective process for extracting antimony from refractory gold ore
To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium Gold and antimony are associated in a number of gold ores with resulting complications in the gold extraction process. The principal mineralogical forms, in which gold occurs in these ores are metallic gold, free-milling, or associated with silicate gangue, as metallic gold associated with stibnite [Sb 2 S 3] will be seen from the processes used to Treatment of antimonial gold ores ScienceDirect

Preparation of Antimony Sulfide and Enrichment of Gold by
Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide Although this process with short flow could eliminate the low-concentration SO 2 pollution, the antimony recovery rate and the antimony content in crude antimony were low. In the treatment of high arsenic and gold-containing stibnite concentrate, the problem of arsenic alkali residue is still prominent, and the loss by gold dispersion is high.Extracting antimony from high arsenic and gold-containing stibnite ore

Extracting antimony from high arsenic and gold-containing stibnite ore
This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.Gold–antimony ores usually contain stibnite (1.5–4.0% Sb), pyrite, arsenopyrite gold (1.5–3.0 g t −1) and silver (40–150 g t −1). Several plants in the USA (Stibnite, Minnesota and Bradly) and Russia have been in operation for some time. There are two commercial processes available for treatment of these ores. •Stibnite an overview ScienceDirect Topics
