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.

Zhang et al. [54] studied the recovery of antimony and bismuth from pres-sure-leached flue dust created during the smelting of cop-per. They used a three-step process consisting of a kerosene desulfurization step, a chloride leaching step, and a final hydrolysis step to recover 95.80 % of Bi and 90.8 % of Sb.

Due to increased antimony-bearing mineral mining/processing over the past few decades, there has been increased deposition of antimony into the environment (Selim, 2012). The anthropogenic sources, stated …

Relation to Mining. Antimony rarely occurs in its native metallic form in nature. It easily combines with other elements, usually including sulfur, to form over 100 different minerals. Of these minerals, only stibnite (Sb2S3) is mined commercially as a source for metallic antimony. Antimony is found in trace amounts in silver, copper and lead ...

Antimony may enter the environment as a consequence of mining and processing of its ores and in the production of antimony metal, alloys, antimony oxide, and combinations with other substances. Antimony released from smelters may remain in particulate quantities in the air, some of which reaches the soil during rainfall where it attaches ...

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 …

The Beaver Brook mine, which operated briefly during 1998, is the only antimony producer in North America. A 400 t/d mill was built a decade ago, and all equipment and other facilities are operational. Mine rehabilitation and development have been completed, the production ramp and 313 meters of drifts are ready for mining to …

Abstract. Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Anti …

The Project is one of the highest-grade, open pit gold deposits in the United States and is designed to apply a modern, responsible mining approach to restore an abandoned mine site and produce ...

This process allows gold to be stabilized in the mineral. However, when the arsenic concentration is low, gold doesn't enter the mineral structure but only forms weak gold-sulphur bonds with the ...

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 were …

Major sources of pollution during the antimony (Sb) mining and processing are mining waste rock, smelting waste, tailings dam, and underground tunnel wastewater. The aim of the present study was to assess magnitude of pollution from Sb mine by taking four types of samples: soil in the mining waste rock zone, soil in the smelting zone, soil …

The 5 Lifecycle Stages of Mining. 1. Exploration & Prospecting Stage. This is the first and most essential step of the mining process: in order to open a mine, companies must first find an economically sufficient amount of the deposit (an amount of ore or mineral that makes exploitation worthwhile.) Geologists are enlisted by the companies to ...

Sample collection, processing, and categorization. Gold mining waste (0–20 cm, ∼1–2 kg) was collected from 30 different sites across Victorian Goldfields, dried ... Antimony leaching from soils and mine waste from the Mau Due antimony mine, North-Vietnam. J Geochem Explor, 220 (2021), Article 106663.
