Techniques for the processing of antimony-bearing ores encompass a wide range of techniques from traditional hand sorting, which is dependent on plentiful and cheap labour, to technologically advanced, capital-intensive mineral processing. The main antimony products in international trade are stibnite and subordinate stibnite-berthierite …
This has sparked efforts to find secondary sources of antimony either through the recycling of end-of-life products or by recovering antimony from industrial process …
Antimony has been highlighted as a critical raw material in the EU owing to its economic significance and high supply risk. Due to the dispersed uses and low antimony concentration of the main antimony end-use, i.e. flame retardant in plastics, little antimony has been recovered from waste plastics to date.
Abstract. 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 …

This approval means that U.S. Antimony now has the only approved North American mine source of antimony for the production and supply of antimony trisulfide to the DOD /DLA for primers in munitions.
The antimony ore hand-selection process is carried out by using the difference in color, luster and shape of the antimony-containing minerals in the antimony ore and the gangue. Although this method is primitive and labor-intensive, it still has special meaning for antimony ore beneficiation. Since antimony deposits are often produced in …
The working conditions in antimony processing have improved markedly over the last 30 years and the workforce has been much reduced in numbers following automation of the process. The health of antimony workers was a concern of Sir Thomas Oliver (1853–1942), who was distinguished in the field of occupational medicine. ...
This paper focuses on the environmental leaching of antimony, a critical mineral, using deep eutectic solvents. Mining residues often contain embedded …
Antimony is a strategic critical mineral that is used in all manner of military applications, including the manufacture of armor piercing bullets, night vision goggles, infrared sensors, precision ...

Antimony Metallurgy. Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. …
Methods of reducing melting and sulfide-alkaline leaching of antimony sulfide concentrates to obtain metallic antimony and antimony trioxide are discussed, and methods of …
The process parameters were optimized by response surface methodology (RSM). Under the optimized conditions, the reduction temperature was 758 °C, the reduction time was 56 min, the reducing agent addition ratio was 0.123, and the molten salt addition ratio was 0.1. An antimony ingot with a yield of 92.19% and a purity of 99.45% …
Antimonial dust is a by-product of lead smelting and an important material for extracting antimony. A new pyrometallurgical process for producing antimony white from the antimonial dust is reported. The process mainly consists of three steps, which are reduction smelting, alkaline refining, and blowing oxidation. First, the reduction smelting …

Antimony telluride (Sb2Te3) is an intermetallic compound crystallizing in a hexagonal lattice with R-3m space group. It creates a c lose packed structure of an ABCABC type. As intrinsic semiconductor characterized by excellent electrical properties, Sb2Te3 is widely used as a low-temperature thermoelectric material. At the same time, …
Antimony is considered a critical and strategically important metal and is used in a wide range of products. This study examines major antimony supply chain …
Published online: 11 Oct 2022. Review. A review of the technologies for antimony recovery from refractory ores and metallurgical residues. Hongbin Ling., Annelies Malfliet., Bart …
Antimony had a similar effect to arsenic on the nickel extraction (Fig. 8), with a decrease in the rate and extent of nickel extraction as the antimony addition to the system increased (i.e. higher percentages of antimony sulphide in the concentrate mixture). Reduced leaching of aluminium from the solids and precipitation of aluminium …
Noble antimony is the carrier of precious metals in the antimony smelting system and has a very high added value. This study proposes a novel, green, and effective vacuum gasification process for purifying antimony and recovering precious metals from noble antimony. Saturated vapor pressure and separation coefficients (β) were used to …
The global Antimony market was valued at USD 981.8 million in 2023 and is anticipated to reach USD 1483.4 million by 2030, witnessing a CAGR of 6.0% during the forecast period 2024-2030.
Antimony is a. chalcophile, occurring with sulfur and the heavy metals copper, lead and silver as a sulfosalt. It. occurs as either a distinct an timony bearing sulfide, such as stibnite ...
This paper describes the Sunshine antimony processing facility. Specifically, the relevant process chemistries involved in concentrate Ieaching, metal electrowinning, and sodium antimonate ...
Because of its excessive brittleness and the difficulty of shaping it, antimony (Sb) has no direct applications, but is extensively used as an alloying element to improve the hardness and strength of other metals. So antimony is present in lead-acid batteries to harden the lead of which the electrodes (grids) are made. Hard lead contains 15-25% Sb.
our research targeted secondary antimony sources from underutilized residues of gold, copper, and lead ore processing, which currently pose environmental concerns. Through meticulous experimentation, we determined that optimal antimony leaching is achieved at 120°C within 2 hours, using a 250 g/L Na 2 S and 60 g/L NaOH mixture.
The traditional method of producing antimony metal is through heat smelting. However, researchers at MIT claim to have accidentally stumbled upon a new method of smelting …
