This study aimed to introduce a vacuum process for recovering and enriching antimony from low-grade stibnite. At the pressure of 10 Pa, by controlling Since antimony trichloride has some estrogenic properties, additional studies are needed to determine if other types of antimony, including antimony trioxide, have the potential to be endocrine disruptors.

1. Introduction. Antimony is a toxic trace element of increasing concern due to its wide distribution in the environment. Antimony has no known biological function (Filella et al., 2002) and can cause serious adverse effects to living organisms above certain threshold concentrations (Kabata-Pendias and Mukherjee, 2007).It can inhibit culturable Antimony ore flotation is the most important dressing method for antimony ore. Antimony sulfide minerals are easy to float minerals, and most of them use flotation to improve the grade of antimonyAntimony Ore Dressing Process LinkedIn

Antimony (Sb), a priority pollutant listed by the U.S. Environmental Protection Agency (USEPA), can cause adverse effects on human health, with particular impacts on skin, eyes, gastrointestinal tract, and respiratory system. In this study, a database of Sb concentrations in the global atmosphere was developed through a survey of measurements published in Oxygen Side-Blown Smelting Process. A domestic antimony smelting plant adopts a side-blown furnace for oxygen-enriched smelting, and the schematic of the oxygen side-blown antimony smelting process is shown in Fig. 2.The molten pool depth is 1100 ~ 2500 mm, and the oxygen lances are installed at the side of the furnace to blow oxygen Analysis of Antimony Sulfide Oxidation Mechanism in

Materials: FCC catalyst; Nickel naphthenate; vanadium naphthenate; antimony compound Steaming: Type 100% steam, Temp 766 °C, Time −18 hrs. Calcination: Temp 677 °C, Time 2 hrs. During the impregnation process of antimony compounds on the FCC catalyst, the drying temperature has been established to range This article investigates the behavior of tin and antimony, both commonly present as trace elements in electrical and electronic waste, in secondary (i.e., sulfur-free) copper smelting conditions. The experiments were conducted in oxygen partial pressure range of 10 −10 –10 −5 atm, covering the different process steps in copper smelting.Behavior of Tin and Antimony in Secondary Copper Smelting Process

Section snippets Antimony mineralogy. The mineralogy of Sb is surprisingly diverse. The element is known to substitute in lesser or greater amounts in many primary sulfosalt and oxide phases, but aside from this nearly 200 primary species that contain essential Sb have been described (Anthony et al., 1990–2003, IMA, 2011).Soil antimony concentrations are typically less than 1 ppm, although soil near antimony processing sites or hazardous waste sites on the US Environmental Protection Agency’s National Priorities List may have concentrations as high as 2550 ppm . Airborne concentrations range from 1 to 170 ng/m 3 . Antimony can be found dissolved in Antimony and Nickel SpringerLink

Section snippets Antimony general aspects. Antimony comes under group 15 of the periodic table with ground state electronic configuration [Kr]4d 10 5s 2 5p 3. 121 Sb (57.21% abundance) and 123 Sb (42.7% abundance) are the two stable isotopes of antimony. Antimony can possess different oxidation states (such as +5, +3, 0, −3 and Antimony is becoming an increasingly critical element as the supply-demand gap is expected to exceed 10% over the period 2015–2020. Antimony production is primarily concentrated in China (90%) and as the industrial demand for this metal surges, attention has to turn towards the recovery of antimony from (industrial) waste residues Antimony recovery from the halophosphate fraction in lamp phosphor
