The problem of antimony leaching from a polyethylene terephthalate bottle is very much different from the leaching of antimony from mining wastes. Each process necessitates custom-made treatment methodologies by taking into account various factors including the speciation and concentration. The current review is focused on this aspect.

Antimony (Sb), a toxic metalloid element, is located in the Group VA of the fifth period of the periodic table of elements. At present, with the wide use of antimony containing products in the world and the corresponding mining activities, a large number of antimony containing waste generated in these processes has also been released to the …

This paper focuses on the environmental leaching of antimony, a critical mineral, using deep eutectic solvents. Mining residues often contain embedded antimony, posing environmental risks. Deep eutectic solvents, known for being low in toxicity, cost-effective, and environmentally friendly, present a promising avenue for sustainable …

Schematic overview of the antimony life cycle, which includes (1) the main value chain between primary mining and final disposal, (2) the major waste streams, …

Thus far, only a new chlorine–hydrolysis process has been commercially used by the Hunan Chenzhou Mining Group Co., Ltd. (Hunan Province, China). Fig. 1 shows this new hydrometallurgical process for antimony extraction. This process involves chlorination–oxidation leaching that inhibits the formation of most impurities in solution.

The purpose of this research was to understand the weathering process and environmental impact of heavy metals and metalloids from the old antimony (Sb) mine sites in Sulzburg. In this study, we examined the mineralogy and whole-rock chemistry and performed soil sequential extraction and water chemical analysis around mine sites.

Antimony has been produced from ores in over 15 countries. As shown in Table 2 (Carlin, 2012), world reserves of antimony are estimated to about 1.8 million metric tonnes.As China, the leading producer, accounts for about 90% of the world's mined production and the vast majority of the reserve base (i.e. reserves consist of …

The antimony ore beneficiation methods mainly include manual separation, gravity separation, flotation, and other methods. Select the beneficiation process of a specific ore based on the physical and chemical properties of the ore type (natural type and industrial type), mineral composition, structural structure, and process particle size of useful …

1. Introduction. Antimony is one of China's four strategic resources, mainly used in flame retardant, alloy, medicine, electronic materials and other fields (Yang and Wu, 2014; Guo et al., 2017).The United States Geological Survey (USGS) shows the world antimony output will reach 110,000 tonnes, of which China will account for 60,000 …

Mining waste rock without smelting process, existed higher antimony content in carbonate bound states and waste sulfur content, would be hydrolyzed to produce sulfuric acid and promote its leaching process as well [16, 17]. Sb release content of mining waste rock increased along with the decrease of pH, and especially reached …

Antimonite ore is processed by hand-picking–flotation or heavy medium separation–flotation to pick out lump ore, rich lump ore, and concentrate that will …

Antimony is a chalcophile, occurring with sulfur and the heavy metals copper, lead and silver. More than 100 minerals of antimony are found in nature. Some of the more …

(e.g., mine tailings, process residues, manufacturing scrap) from the production of lead, copper, gold, and antimony [7]. The large production volumes, especially for copper and lead, mean that these residues have the potential to replace a large portion of the primary antimony production [7]. Secondary antimony sources also include end-of-life

The Xikuangshan Sb mine is an active mine whose mining history traces back to 1897 (Wen et al. 2016).Stibnite (Sb 2 S 3) is the main ore mineral, occurring with pyrite, arsenopyrite, pyrrhotite, and sphalerite (Wen et al. 2016).Hundreds of smelting plants, dense residentials, and a large amount of solid mining waste such as smelting …

Antimony Market to reach USD 2.9 Billion by 2032 - Antimony is a chemical element and exists in both metallic and non-metallic forms. The metallic form is bright silver and brittle material. Non-metallic form of antimony is grey powder. Antimony is a stable element in dry air and is inert to acids and alkalis.

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 …

Antimony is an important mineral commodity used widely in modern industrialized societies.
