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 …

The first sample contained 10.5 ppm gold with high arsenic and antimony. The second sample had a low gold content (2.5 ppm) but a high silver content (160 ppm). The first series of test work focused on the determination of conditions for extracting gold from the samples ground to − 75 μm.

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 ...

The ore bodies mainly occur in lamellar, quasi-lamellar and lenticular forms in the altered rocks, and are strictly controlled by anticline structure. In terms of space, elemental paragenesis-separation takes place between gold and antimony deposits, i.e. the gold deposit has antimony ore spots, and the antimony deposit has gold ore spots.

The pretreatment of an antimonial refractory gold and silver ore was investigated using alkaline sulphide leaching. The ore assayed 20 g/t Au and 220 g/t Ag and contained predominantly quartz/clay and barite, and to a lesser extent, sulphides such as pyrite, stibnite, sphalerite, zinkenite (Pb 9 Sb 22 S 42) and andorite (Sb 3 PbAgS …

Preparation of Antimony Sulfide and Enrichment of Gold by Sulfuration–Volatilization from Electrodeposited Antimony. 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….

Orogenic antimony-gold deposits contribute significantly to the global antimony resource base. China's orogenic antimony-gold deposits are primarily in southern Tibet. Investigations indicate that antimony combines and migrates with sulfur hydroxides in ore-forming fluids. Previous research on fluid inclusions in orogenic …

Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …

The Jiangnan Orogen, located between the Yangtze and Cathaysia Blocks in southern China, hosts significant gold (hereafter Au) and antimony (hereafter Sb) resources (Fig. 1; Deng et al., 2017a, Xu et al., 2017, Hu and Peng, 2018).This well-endowed orogen ranks as the largest Sb resource in the world and the third largest Au …

The spatial, temporal, and genetic relationships between antimony and gold mineralization remain a key problem in ore geology. There is general agree ment that antimony …

A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of antimonite. 24% Si in the form of quartz, small quantities of Pb, Fe, Cu, and Ni as well as 63 g/t gold, 60% of it as visible gold.

The southern Tibet Au Sb metallogenic belt in the Himalayan orogen consists of more than 50 gold, gold–antimony and antimony lode deposits, and associated placer gold deposit.The deposits are hosted in a Mesozoic metamorphosed turbidite sequence of the Indian passive continental margin.The Zhemulang Au deposit, Mazhala Au Sb …

Historically and economically, antimony is the second most important metallic commodity in Victoria, after gold. The only significant ore mineral of antimony, stibnite (Sb 2 S 3), is widespread as an accessory mineral in gold-bearing quartz veins, particularly in veins that intersect the Silurian – Early Devonian Murrindindi Supergroup ...

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. Measured & Indicated Mineral Resource of 65.5% available for conversion to Ore Reserve.

Arsenic-containing antimony gold concentrate (As-Sb-Au ore) is an important raw material for antimony and gold extraction [1–3]. Antimony often exists in the form of stibnite and usually needs to be removed before gold extraction [4–7]. Zhang et al. [8] proposed a slurry electrolysis (SE) method to pretreat this As-Sb-Au ore.

Cementation by milky quartz veins containing gold-bearing metasomatite leads to the formation of breccia-type ore-bearing gold–antimony mineralisation. The veins lack gold ore fragments, with the milky quartz veins containing only antimony ore with small quantities of base metals. Genetically, the veins formed in the Hat Han ore deposit …

Refractory gold ore generally refers to ore with less than 80% cyanide leaching rate. There are many reasons for refractory behavior: gold is locked within pyrite/arsenopyrite (Zhang et al., 2016b), carbon-containing substances exist and gold combines with arsenic, antimony and other characteristic elements (Xing et al., 2019). In …

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 …
