The Sarylakh and Sentachan Gold-Antimony Deposits, Sakha-Yakutia: A Case of Combined Mesothermal Gold-Quartz and Epithermal Stibnite Ores October 2010 Geology of Ore Deposits 52(5):339-372

Consequently, complexities of ore mineralogy pose a lot of mineral processing challenges (Feng and Deventer, 2010). Gold can be found in complex sulfide minerals in particular, pyrite and arsenopyrite (Asamoah et al, 2018). In refractory gold ores, the gold is highly encapsulated in the sulfide matrix and pre-treatment is an important

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 …

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 …

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 …

Stibnite, jamesonite, and antimony-gold ores are the most common sources of antimony. The two formers are typically found with lead ores in nature . Antimony-gold ores mostly consist of gold and …

: 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 …

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-gold ores …

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 …

The antimony in refractory gold ores was selectively removed by ultrasound with alkaline sodium sulfide. The removal rate of antimony reaches 94.50% under the optimum conditions: the ultrasonic power is 1500 W, the Na 2 S concentration is 2 mol/L, temperature is 55 °C and time is 60 min and the NaOH concentration is 1 mol/L. …

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. ...

The traditional treatment method of antimony minerals is the smoke method [8,9]; this is because antimony–gold ore contains gold and other minerals, and gold is often associated with sulfides, such as …

11. Antimony deposit; 12. Gold-antimony deposit; 13. Antimony polymetallic ore; 14. City. Organic ma 4er plays a crucial role in the migration and enrichment processes of min-eralizing elements, particularly in the formation of metallic sedimentary deposits [6 8]. SigniÞ cant quantities of liquid hydrocarbons can be …

This process provides a positive guidance for the extraction of antimony from antimonial refractory gold ores owing to high removal ratio of antimony and low …

The only simple sulphide mineral of antimony of importance is stibnite, SbS3, containing 718% antimony when pure. It is lead-grey, has a densityof 45 to 46 and melts at 546C. It is both friable and sectile (Hardness 2 on Moh's scale) and, as a result, slimes very readily during milling.It is commonly associated with pyrite and arsenopyrite other minerals …

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 …

1. Introduction. At present, more than 35% of China's gold resources (with a total amount of more than 1,000 tons) are difficult to be exploited and smelted, and about 700 tons of gold ores with high arsenic, antimony or sulfur are difficult to be directly cyanide leached (Lei et al., 2016).However, as the gradual depletion of easy-to-treat …

No visible gold is found in the antimonite of the quartz–antimonite veins, but atomic-absorption analysis reveals few ppm or more gold. Point X-ray analysis indicates …

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 …

The Stibnite gold project is located approximately 245km north-east of Boise and approximately 16km east of Yellow Pine, in Idaho, US. The project covers a total area of approximately 27,104 acres. The Stibnite ore body is underlain by pre-Cretaceous basement sediments of the Idaho Batholith, Tertiary intermediate to felsic intrusions and ...

Also, marcasite, cinna- bar, and native Ag, Sb, and Au are found here. Secondary aureoles of Au in the Bakyrchik ore field do not always coincide with the Sb aureoles (Fig. 3). Antimony mineralization in the Kuludzhun ore district was detected in several ore localities with gold-sulfide and vein goldâ€"quartz mineralization.

The metallogenic regularity of gold deposits was preliminarily summarized and 71 gold metallogenic series were proposed in China. This suggests that it is necceary to deepen the study on metallogenic regularity of gold deposits and to provide the theory guide for the ore–prospecting for gold resources in China.

In general, it is suitable for antimony containing refractory gold ores. The principle is that gold can be enriched into smelting product directly. The refractory gold ore with a high content of antimony (25.0–35.0% Sb, Au 30 g/t) is commonly used as an important raw material in the smelting of antimony . The melting products are antimony ...

Improvements in mineralogical identification and understanding of the chemistry of the cyanidation process with antimony present are leading to improved …

However, a key difference between the gold and antimony deposits occurs in the nature of ore fluids. At Qinglong, Sb ores were formed in early-ore stage, Chen et al. (2018) estimated that the Sb-rich ore fluids in this stage are medium to low temperatures (161–294 °C, mean 220 °C), with wide salinity range (0.35–13.18 wt.% NaCl eqv.) and ...

China leads the global antimony production (67% on an average from 2015 to 2019) followed by Russia and Tajikistan. Antimony has been applied in the industry (plastics, etc.) and new/emerging technologies (cell panels, infrared, etc.) where antimony xide (Sb 2 O 3) is its most produced and used compound. With technological …

Abstract. 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 (Sb2S3), the antimony (Sb ...
