As of 31 December 2019, of Australia's Ore Reserves of antimony are attributable to the Costerfield mine in Victoria (Table 2). Costerfield produces antimony as a by-product to gold and is Australia's only antimony producer. Ore Reserves were down 73% from 2018 levels owing to reclassification of the Hillgrove deposit in New South Wales.

Abstract. Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so …

Ultrasound-intensified Leaching of Gold from a Refractory Ore. The effect of ultrasonic energy on the pretreatment and leaching of gold from the refractory ore was investigated. Firstly, the refractory ore was pretreated with …

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.

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 …

In order to overcome this problem, Yang et al. utilized the sodium sulfide to extract the antimony from refractory gold ore, and the leaching recoveries of antimony and arsenic were 96.64% and 0. ...

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 …

The paper also describes a process that was developed for processing of goldantimony concentrates and precipitation of antimony and gold. An antimony recovery exceeding 90–95% can be achieved ...

The 254km2 Hillgrove Project contains six key mining areas within 48 granted Mining Licenses. Hillgrove is the largest Antimony Mineral Resource in Australia and is ranked #8 in the world, making it a strategically significant deposit. Antimony is a critical mineral for multiple countries including the US, EU and Australia.

Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations …

The association of gold and antimony in many ores provides additional complications in the gold extraction process. Improvements in mineralogical …

The technology of concentration of the sulfide antimony-arsenic gold-bearing ore containing 3.6 g/tn Au, 0.3% Sb, and 0.4% As is developed. This technology implies the flotation separation of antimonite and arsenopyrite into separate products and allows them to perform in various cycles, increasing production efficiency due to a decrease in …

Antimony has a negative effect on the gold extraction from antimony–gold concentrate, and it is necessary to remove antimony in advance. For a high calcium low antimony–gold concentrate (Ca–Sb–Au ore), this study proposed to pre-remove antimony using slurry electrolysis in HCl–CaCl 2 system. The results indicated that the optimal …
