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. Stibnite forms some of the most outstanding natural crystals that exist, in way of sharpness, luster, and size.It can form in groups of huge metallic lustered crystals that are elegantly crafted and exceptionally shiny.

The Mineral antimony. Antimony is a native element that can occur in a natural state, but it is rarely pure. It almost always contains some arsenic, and may also contain traces of silver, iron, and sulfur. On a fresh or preserved surface, Antimony has a tin-white color with a slight blue tinge. Otherwise, it is dark gray due to tarnish.

Antimony provides hardness to metals like tin and lead while decreasing the degree of oxidation. Aside mechanical properties, antimony affects color of its alloys with copper. Copper–antimony alloys with higher than 6–7 wt% of antimony turn their color towards blue as antimony content increases .

Antimony ore can be divided into antimonite, cubismite, antimony ochre, etc. Due to the difference in the nature of the ore, the process used is also different. Commonly used beneficiation processes include manual separation, gravity separation and flotation . This article briefly introduces these three commonly used antimony ore beneficiation processes.

Flame-retardant grades of antimony oxides are manufactured from either antimony metal or the sulfide ore by oxidation in air ...

Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.

In the first half of the 1500s, Vannoccio Biringuccio wrote a description "Concerning Antimony and Its Ore". This is an alchemical work. Biringuccio describes antimony sulfide as either "a monstrosity among metals" or, alternatively, "a material that is about to reach metallic perfection, but is hindered from doing so by being mined too soon".

Antimony is a regarded as a cooperative metal because it works best when it is combined with another metal, notably lead, brass and bronze. It is actually a metalloid that does not react chemically as a metal but has metal-like appearance & physical properties. It is a protective metal and teaches the values of transformation and adaptability.

6.1 Antimony (Stibnite Ore) Antimony deposits and prospects in the form of quartz- stibnite veins and replacement bodies are scattered in the Slate belt between Papun and 15°N. Clegg gives a summary description, based on Heron in Clegg (1944a), of the deposit at Thabyu village (15°35′N, 98°07′E), 70 km southwest of Thanbyuzayat.

Antimony is often found in other ores as well, e.g., silver, copper, and lead. The pure element antimony is produced from the ore by roasting it to form the oxide, then reducing the oxide with carbon or iron; often a flux of sodium sulfate or sodium carbonate is used to …
