A Review on Pyrometallurgical Extraction of
Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction Introduction. Antimony (Sb, stibium) is a semimetallic element that belongs to the vanadium family (Group VA) of the periodic table and shares certain chemical and physical properties with lead, arsenic, and bismuth [1 ]. In nature, antimony is associated with sulfur as stibnite and occurs in ores with arsenic.Antimony an overview ScienceDirect Topics

Antimony release from contaminated mine soils and its
Antimony (Sb) can pose great risks to the environment in mining and smelting areas. The migration of Sb in contaminated mine soil was studied using lysimeter experiments. The exchangeable concentration of soil Sb decreased with artificial leaching.The concentrations of Sb retained in the subsoil layers (5–25 cm deep) were the 1. Introduction. Antimony (Sb) is one of the most commonly used metallic element, with global reserve of 1.9 million tons. According to recent report, almost 80% of Sb production was concentrated in China, Russia, and Bolivia (United States Geological Survey, 2021).By 2020, China was the leading producer of Sb worldwide, accounting for Antimony contamination and its risk management in

Antimony: The Most Important Mineral You Never Heard Of
The Stibnite mine ended up producing fully 90% of America’s demand for antimony for the duration of the War and was key to producing 40% of the tungsten steel needed for the military effort.The Xikuangshan (XKS) mine, the world’s largest antimony (Sb) mine, was chosen for a detailed Sb isotopic signature study owing to its historical Sb contamination of water systems. Hydrochemical data, in particularδ 123 Sb values, were analyzed to identify the Sb source and predominant geochemical processes that affect Sb mobilization inAntimony (Sb) isotopic signature in water systems from the

Other heavy metals: antimony, cadmium, chromium and mercury
This chapter considers the heavy metals antimony, cadmium, chromium and mercury employed as building materials with respect to their history, structure, properties and uses. The biomonitoring, toxicological mechanisms and health effects of these metals as regards indoor pollution and remedial measures are discussed. Previous chapter. Antimony (Sb) is found in nature as the sulfide mineral stibnite and is widely used in industrial applications such as batteries and flame retardants (Anderson 2001; Bergmann and Koparal 2011; Ilgen et al. 2014).Although Sb occurs at low concentrations and exists in several oxidation states in nature, industrial processes like Energy and environmental impact assessment of a passive

Fuzzy association rule-based set-point adaptive optimization
Froth flotation is a complicated process which is difficult to establish its first-principle model. Due to the fluctuations in the grade of raw ore, adaptively adjusting the set-points is extremely important in the flotation process. The inappropriate set-points easily lead to the instability of the process. This paper presents a fuzzy association rule-based set describe technologies used to mine antimony. 18 05 2021 China s antimony mine production amounted to approximately 80 000 metric tons in 2020 thus China was the leading producer of antimony in the world. الدردشةdescribe technologies used to mine antimony

As highly toxic and carcinogenic substances, antimony and arsenic often coexist and cause compound pollution. Heavy metal pollution in water significantly threatens human health and the ecological 1. Introduction. Antimony is a hard, lustrous, silvery-grey metal. Antimony is unevenly distributed throughout the crust of the Earth, with China (32%), Russia (23%) and Bolivia (21%) as the top three countries in terms of their antimony reserves (Ding et al., 2021).It is extremely difficult to beneficiate antimony since the average abundance of Dynamic material flow analysis of antimony resources in China

Mine Water as a Resource: Selective Removal and Recovery
The objective of this study was to evaluate the feasibility of combined modular processes to selectively remove Sb from mine-impacted waters in an Arctic environment in order to fulfil local environmental criteria for discharged waters. Novel ion exchange, selective extraction and ultrafiltration, electrocoagulation, and dissolved air Mining and smelting activities of the world largest Antimony (Sb) mine which is located at Xikuangshan area of Hunan Province, China, constitute important sources of Sb pollution throughout the rivers in or around the mine.

Removal of antimony (Sb(V)) from Sb mine drainage:
Antimony (Sb) is a metalloid element widely used in production of flame retardants, textiles, papers, adhesives, tires, brake linings and plastics. Sb and its chemical compounds were listed as priority pollutants by USEPA and EU due to their toxicity to humans, plants and microorganisms (Zhang et al., 2010).Antimony (Sb) and its compounds, as global priority contaminants, are found in soils and water due to natural and anthropogenic sources. Elimination of Sb from water and wastewater is necessary because of its potential harm to the ecosystem and human health. This study aims to present different technologies used for SbAntimony removal from water and wastewater by

The Legacy of Potential Environmental Soil Contamination in an Antimony
In the Valongo Belt, with an extension of about 90 km, located very close to Porto, northern Portugal, dozens of ore deposits of various metallic minerals and coal were exploited in the 19th and 20th centuries. One of the metals most intensely exploited was antimony, with or without associated gold mineralization. This research intends to Antimony (Sb) is a metalloid widely present in plastics used for food contact packaging, toys and other household items. Since Sb can be released by these plastics and come into contact with humans, health concerns have been highlighted. The effect of Sb on human tissues is yet controversial, and biochemical mechanisms of Antimony contamination, consequences and removal
