Gold–antimony ores usually contain stibnite (1.5–4.0% Sb), pyrite, arsenopyrite gold (1.5–3.0 g t −1) and silver (40–150 g t −1). Several plants in the USA (Stibnite, Minnesota and Bradly) and Russia have been in operation for some time. There are two commercial processes available for treatment of these ores. •

Similar variations in δ 123 Sb values of stibnite and mine water suggest that the Sb isotope composition in mine water may be affected by surrounding stibnite ores. However, the difference in Sb isotopic signatures between stibnite and mine waters and the variation in both Sb concentrations and Sb isotopic signature in the mine waters …

Antimony. A native element, antimony metal is extracted primarily from stibnite, which contains 72 percent antimony and 28 percent sulfur. Stibnite is mined in only a few countries, with China being its largest producer. Antimony is used for many technological and industrial purposes. Antimony is used as a hardening alloy for lead, especially ...

At Qinglong, economic Sb ores contain coarse-grained stibnite, jasperoid quartz and fluorite, whilst the sub-economic Au-Sb ores comprise dominantly veined quartz, arsenian pyrite and fine-grained stibnite. Three generations of ore-related pyrite (Py1, Py2 and Py3) and two generations of stibnite (Stb1 and Stb2) are identified based on their ...

Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries. The metal also finds applications in solders and other alloys. Antimony trioxide is the most important of the antimony compounds and is primarily used in flame-retardant formulations.

The mineral is potentially toxic primary sulfide ore of antimony. Stibnite is a typical hydrothermal deposit associated with other sulfide minerals and is the principal source of …

Stibnite-bearing ores continue to be the main source of this critical element, although its sourcing from secondary resources (e.g. mine tailings) is becoming increasingly relevant yet...

Though stibnite is among the most predominant Sb-bearing mineral phases in most Sb deposits, little is known about the trace elements and their substitution mechanism in stibnite that are valuable to better decipher the genesis of Sb deposits. This study determined quantitatively the trace element compositions of stibnite from two …

Banxi is the most representative deposit in the region with vein-type Sb mineralization hosted in Neoproterozoic clastic rocks, stibnite developing in ores, and arsenopyrite mainly occurring in ...

Natural variation in the isotopic composition of Sb in stibnites (Sb ores) was explored using multi-collector ICP-mass spectrometry (MC-ICP-MS).A method for isolating Sb (after acid digestion) without introducing artificial mass fractionation was developed, based on the use of a combination of cation exchange chromatography using Dowex AG50-X8 resin and …

The main antimony phase of antimonial refractory gold ores is stibnite (Sb 2 S 3). Sodium sulfide is proposed as leaching agent to remove antimony from antimonial refractory gold ores . Meanwhile, sodium hydroxide is also used to prevent the hydrolysis of sodium sulfide. The main equations are expressed as follows:

The Mineral stibnite. Stibnite is named after the latin stibium, which is the old name of the element antimony (Sb). Stibnite was and continues to be the primary ore of antimony.
