A two-stage roasting process, similar to that used for arsenic sulfide ores, can also volatilize antimony oxides and prevent adverse reactions such as the production of metallic antimony, which can coat the surface of gold particles (Nagy et al., 1966) or the formation of silver glasses in high-silver ores (Matsukawa and Sakai, 1956).
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 treat such …
Orogenic antimony-gold deposits contribute significantly to the global antimony resource base. China's orogenic antimony-gold deposits are primarily in southern Tibet.

conventional leaching process. The gold ores that contain As must be crushed in order to expose the gold for leaching with an appropriate gold leaching agent (Yanget al, (2008); Zhou et al, 2009) In order to maintain the sustainable use of gold resources, effective pre- treatment and processing of complex gold ores
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 were …
Gold-bearing ore from a Russian deposit that contains 4.9 g of gold per ton of ore, 0.2% antimony, and 0.3% arsenic was subjected to concentration. The flow chart that was developed for recovering antimony while concentrating the gold-bearing ore (Fig. 1 ) includes collective flotation of the sulfide minerals and selective flotation to separate ...
In the northwestern margin of the Youjiang basin (NWYB) in SW China, many Carlin-like gold deposits are highly antimony (Sb)-rich, and many vein-type Sb deposits contain much Au. These deposits have similar ages, host rocks, ore-forming temperatures, ore-related alterations and ore mineral assemblages, but the Au and Sb metallogenic relations and their ore-forming process …
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. ...
A basic technological flowsheet diagram for flotation gold-antimony processing for the Olimpiadinskoe deposit has been developed; it includes two redistributions: production of metallic antimony ...
China is a net importer of antimony metal. Currently, 86% of Australia's antimony exports are sent to China for processing. Investing in processing capacity and infrastructure for lower-grade antimony products may offer limited strategic value for the United States, as these products will still be available under China's restrictions.
It has been testified by some practice process that this type of arsenic-antimony gold ore can be efficiently treated in fire matte smelting systems mixed with copper concentrates (Avarmaa et al., 2016; Roghani et al., 2000). ... on the basis of the occurrences analysis of gold and antimony in Sb-bearing refractory gold ore, the process ...
Refining techniques are employed to further purify and process antimony after it has been extracted from its ore. These techniques aim to remove impurities and obtain high-purity antimony products suitable for specific applications. Here are some commonly used refining techniques in antimony processing: 1. Pyrometallurgical Refining
It can be seen from Eq. () that Sb 2 S 3 is deposited on the surface of gold particles, forming a dense product layer and hindering the diffusion of CN − and O 2 to the gold particles, leading to low leaching ratio [3, 4].Effect of Antimony on Pretreatment Process. The melting point of antimony compounds, generated in the roasting process of antimonial …
The mineralization process in gold deposits suggests that it is better to enrich gold with arsenic and antimony rather than removing them from refractory gold ores . The smelting process also shows that there is a proportional relationship between the contents of antimony and gold in antimony-ferrous matte.
Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of Germany.
