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) forms stable ...

Techniques for the processing of antimony-bearing ores encompass a wide range of techniques from traditional hand sorting, which is dependent on plentiful and cheap labour, to technologically advanced, capital-intensive mineral processing. The main antimony products in international trade are stibnite and subordinate stibnite-berthierite …

Current processing technology for antimony-bearing ores 551 Turhal antimony plant, Turkey Turhal processes a type of ore with quartz veins and stibnite as the sole ore mineral [8]. A certain amount of calcite and pyrite is present in the ore. Graphite and arsenic-bearing minerals, which are more troublesome from the point of view of …

The main methods used for the hydrometallurgical selection of gold and antimony are based on alkaline sulfide leaching. Alkaline sulfide leaching can also be used to extract chemically active antimony minerals from gold-bearing ores and concentrates before their cyanation.

This paper outlines the fundamentals of alkaline sulfide hydrometallurgy and its successful application to arsenic, antimony and mercury bearing ores, concentrates, by-products, and other ...

The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a low-temperature sulfur-fixing smelting process. This article reports …

Volcanic activity and weathering of Sb-bearing crustal rocks/minerals are two important natural sources (Li et al., 2018).

Antimony leaching from tetrahedrite-bearing ores was typically carried out by using Na 2 S-NaOH solutions. In the current paper, the detail mechanism of …

Majority of antimony-bearing ore deposits are associated with the subduction-related western Pacific plate boundaries, especially in east and south-east …

Hydrometallurgical methods can be used to treat gold, arsenic, antimony, tin, and mercury contained in minerals, concentrates, and ores, as well as in complex compounds bearing any number of metals.

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 is a valuable mineral component in gold-bearing ores though it is an attribute of a rebellious ore as a chemical depressor of gold in cyanide treatment circuit [4]. Each of more than 18 antimony minerals, which can be present in gold-bearing ores, behaves specifically in ore preparation and cyanation.

To understand the leaching characteristics of hazardous Sb, As, Pb and Cr from antimony minerals, 12 samples of antimony-bearing ores from eight large mines from China distributed in Hunan, Yunnan ...

Written documents must speak of antimony-bearing ores (e.g., stibnite) rather than metallic antimony. Thus, while referring to textual records in the following paragraphs, this distinction should be noticed. Antimony was not among the goods imported from Aššur, though it was traded by Assyrians in Anatolia [62: p.85].

Microorganisms are widely used in many technical processes. One of the main purposes of this paper is to report some of the changes which occur in mineral ores under the influence of different types of bacteria. Studies on these changes have made it possible to...

The pH-dependent leaching of antimony (Sb) and arsenic (As) from three typical Sb-bearing ores (Banxi, Muli and Tongkeng Antimony Mine) in China was assessed using a pH-static leaching experiment.

Approximately 36% of antimony was bioextracted by fungus from antimony bearing ferric oxyhydroxide after 14-day cultivation when the 8.9 mg·L −1 antimony concentration was used for pre-adsorption. However, no statistically significant change of antimony content in ferric oxyhydroxides was observed after cultivation when initial 48 …

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 …
