As part of process verification, pilot plant trials for the treatment of the uranium-containing effluent were performed (Foster et al.). These generated antimony-laden effluents high in phosphate for which antimony removal via ferric chloride dosing could be trialled (Table S2). A range of iron dosages were tested.
Antimony removal is an important requirement in nuclear industry as well due to the formation of its radioactive isotopes during power plant operations. Thus, better antimony remediation or removal techniques can have wider applications ranging from domestic water treatment and industrial effluent remediation to safe isolation of radioactive ...
Antimony (Sb) is introduced into soils, sediments, and aquatic environments from various sources such as weathering of sulfide ores, leaching of mining wastes, and anthropogenic activities. High Sb concentrations are toxic to ecosystems and potentially to public health via the accumulation in food c …
The antimony processing plant employed local people to operate the machinery and bag the product but in 1974 the plant was abandoned. No clean-up or remediation was done, and the site was eventually sold to a private owner.

Antimony is a dissolved state in water that has a strong migration ability, and when antimony is adsorbed to particles or sediments in water, its migration ability will be reduced. The reduction process can release antimony from sediments into the water environment. The transformation process of antimony is Sb(III) → Sb(V) → Sb(OH) 6 − ...
Where gold is associated with arsenic, antimony, tellurium, and certain other minerals, it is often only partly soluble in cyanide solution. The difficulty is usually more of a physical than a chemical one but special methods of treatment may be required. Gold Leaching & Processing of Arsenic Ore Mispickel (Arsenopyrite: FeAsS).6
The specific mineral processing process needs to provide antimony ore samples from the customer to determine the best mineral processing plant. The selection of suitable antimony ore beneficiation equipment can better improve the flotation effect and enhance the economic benefits of the enterprise.
This process is called "chemical decontamination" and it is routinely carried out in the operating nuclear power plants worldwide (Balaji et al., 2006; Manjanna et al., 2002; Rufus et al., 1998; Ocken, 1999). In majority of the nuclear power plants, antimony-impregnated graphite pump seals and bearings are used.
This study aimed to introduce a comprehensive process for separating and recovering antimony from a complex stibnite concentrate. Antimony is first leached through a chlorination–oxidation procedure to obtain SbCl 3 solution. Antimony is then recovered in the forms of cubic crystal Sb 2 O 3 (99.9%), high-purity cathode antimony (99.98%), …
Sb release characteristics of blast furnace slag, mining waste rock and tailing sand were investigated in static immersion and dynamic leaching test. These three kinds of waste samples were collected from the antimony mine in Lengshuijiang, China, produced in mining smelting process. Effects of solid/liquid ratio, sample size and pH of leaching …
UK-based metallurgical engineering firm Inprotec has designed and developed drum-style furnaces for a "clean" antimony and gold plant owned by Strategic and Precious Metals Processing (SPMP) …
The authors also introduced a processing plant for Sb-Au-bearing alloys and demonstrated the successful electrolytic refining and production of cathode antimony and noble metal slurry [39, 43]. Kanarskii et al. [ 38 ] investigated the concentration and isolation of antimony and arsenic in Sb-As-bearing gold ores by flotation.
While producing 66,000 tons a year of battery-grade lithium carbonate, the mine may cause groundwater contamination with metals including antimony and arsenic, according to federal documents. The ...

Pentavalent organic antimony compounds have been used for the last 60 years. The two predominant forms are sodium antimony gluconate (sodium stibogluconate) and meglumine antimoniate (N-methyl-D-glucamine or Glucantime) (Haldar et al. 2011). In the treatment of parasitic diseases, the patient receives multiple injections of the antimony compounds.

The antimony process was able to go from an initial concentration of 3.5-g/L Sb to about 0.07-g/L Sb and keep the current efficiency much higher than that in conventional liberator processing.10 Several problems with liberator processing have caused some refineries to abandon it in favor of newer processes, like IX columns or …
4. The mineral processing of antimony Originally antimony was mined and hand sorted to effect con-centration. Since the bulk of primary production is in China, where labor is plentiful and cheap, surprisingly, hand sorting still finds a large application.
