Beneficiation of antimony oxide ore: A review SpringerLink
This work presents the latest research on antimony oxide ore beneficiation, outlining recent progress and developments in antimony oxide ore Antimony has a range of industrial uses in batteries, chemicals, ceramics and glass but by far the most important is in fire retardants The economically most Antimony Critical Metals Handbook Wiley Online Library
Onestep extraction of antimony from lowgrade stibnite in
Introduction Antimony is primarily used for the production of alloys, flame retardants and brake pads (Uexküll et al, 2003) For industrial production, the pyrometallurgical methods involving volatilisation and reduction of sulphide ores were the primary means to extract antimony, which are high temperature (>1473 K) and high Antimony is a nonrenewable strategic mineral resource and an indispensable and important raw material for modern industrial development With the highintensity resource mining in recent years, the consumption of antimony resources is too large Antimony beneficiation methods are important to improve the recovery rate of Three Methods To Antimony Ore Beneficiation And Processing
Antimony contamination, consequences and removal techniques:
All of antimony and antimony compounds have toxicity to the human body Furthermore, the sources of Sb pollution are diverse For example, natural weathering of Sb ore, mining, smelting, the burning of fossil fuels and the wide use of antimony compounds increase the concentration of Sb in the geochemical environment, causing While discussions abound about the exploitation of mines, mining settlements, possible origins of artifacts, resources of copper, arsenic, and especially tin to improve our knowledge about Anatolian Bronze Age mining and metallurgy, uncommon alloying practices including the use of antimony, nickel, or lead have long remained in Why did the use of antimonybearing alloys in Bronze Age
Removal of antimony from antimony mine flotation wastewater
Antimony in the environment comes from natural processes (ore weathering, volcanic activity) and human activities (mining and smelting, use of antimony containing products, fossil fuel combustion, etc) Similar to many elements, the toxicity of antimony is closely related to its chemical form, and the toxicity of Sb(III) is much higher In the past, workers were exposed to high levels of antimony trioxide from mining or smelting, a process that uses heat to extract a metal from its ore In the general population, exposure can occur through breathing contaminated outdoor air, or contact with fine dust from the wear and tear of flameretardanttreated products containing antimony RoC Review of Antimony Trioxide National Toxicology Program
Availability, Toxicology and Medical Significance of Antimony
Antimony has been known and used since ancient times, but its applications have increased significantly during the last two centuries Aside from its few medical applications, it also has industrial applications, acting as a flame retardant and a catalyst Geologically, native antimony is rare, and it is mostly found in sulfide ores The Antimony makes batteries stronger and resistant to corrosion Most antimony occurs in scattered ore bodies that cannot be readily exploited by largescale mining methods Often, antimony is produced as a byproduct of mining other metals, such as gold, lead or silverMineral Resource of the Month: Antimony EARTH Magazine
Pollution Characteristics of Sb, As, Hg, Pb, Cd, and Zn in
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 beneficiation methods for antimony oxide ore In view of this goal, we present a brief overview of recent advances in antimony oxide ore beneficiation processes, based on a review of sorting methods used for antimony oxide ores, both nationally and internationally This review provides critical information forBeneficiation of Antimony Oxide Ore: A Review Springer
Antimonycomplexed heavy metal wastewater in antimony mining
Furthermore, wastewater generated during the ore beneficiation and smelting processes of antimony mining is also an important source of antimony compound heavy metal wastewater in antimony mining areas In the ore beneficiation and smelting processes, substances containing antimony and other heavy metal components are Guangxi Dachang Mining Bureau treated a sulfurantimonylead concentrate (25–29% Pb, 16–20% Sb), the byproduct of tin production in such a process, using a single PM; Alekseev, AN A Review on Pyrometallurgical Extraction of Antimony
Antimony and Antimony Compounds Grund Wiley Online
Antimony metal is recovered from ore primarily by pyrometallurgical techniques Because rich ores are becoming rare, greater recourse is being taken to intermediates in processing and metal industries Hydrometallurgical processing is suitable for some ores containing precious metals and is used by the Sunshine Mining Co (USA)The industrial methods for refining antimony from stibnite are roasting followed by reduction with carbon, the typesample was collected from the Sala Silver Mine in the Bergslagen mining district of Sala, Västmanland, Sweden The extraction of antimony from ores depends on the quality and composition of the oreAntimony
Antimony in the metallurgical industry: A review of its chemistry
The extraction of antimony ores from stibnite (Sb 2 S 3 ) and its subsequent burning produces valuable antimony oxides (Sb 2 O 3 and Sb 2 O 5 ) and Sb metal (Multani et al,2016), but also acidINTRODUCTION Antimony (Sb) (atomic number 51; atomic mass 12175 g/mol; density 6684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3)The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure The exposure to and health effects of antimony PMC
Antimony speciation and contamination of waters in the
Water samples from Xikuangshan (China), the world largest antimony (Sb) mine with a Sb mining and smelting history of more than 200 years, were analyzed These water samples ranged from stream water in the vicinity of the mining and smelting area that received seepage from ore residues to the underground minepit drainage The In recent years, international research on the toxicity of the heavy metal, antimony, has gradually changed focus from early medical and pharmacological toxicology to environmental toxicology and ecotoxicology However, little research has been conducted for sources identification and risk management of heavy metals pollution by longterm Health and ecological risk assessment of heavy metals Springer
