Metallurgy. LIQUATION: Liquation is the melting of stibnite into "crudum" or "needle antimony". It is carried out between 550 and 600 degrees C. If the temperature is lower, the recovery is poor. If the temperature is any higher, the stibnite volatilizes into oxide. This method is …
The increasing gap between demand and supply of antimony meant that in 2011 the European Commission considered this metal as a critical raw material.1,2. Antimony mainly occurs in the form of sulfide ores, such as stibnite, tetrahedrite, andorite, jamesonite, and zinkenite.
Abstract This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.

Stibnite is a lead-gray mineral, usually occurring as striated prismatic crystals, that is made up of antimony sulfide (Sb2S3) and is the main ore of antimony. It often forms groups of long, shiny metallic crystals radiating out at different angles, which look like …
In the early 18th century, Jöns Jakob Berzelius chose the periodic symbol for antimony (Sb) based on stibium, which is the Latin name for stibnite. Antimony is nonmalleable, hard and brittle and can be crushed to a powder. Compared with metals, antimony is a …
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.
Antimony (Chemical symbol Sb) is classified as a minor metal, growing in strategic importance. It can be found in over 100 difference mineral species, typically in association with elements such as mercury, silver and gold. The principle ore mineral of antimony is stibnite. The main use for antimony is as a trioxide additive in the chemical and ...
Antimony losses in tailings may be caused by the poor response to floatability of native antimony and antimony oxides (e.g. cervantite, valentinite, senarmontite) occurring in stibnite-bearing ores, and by the relatively slow floatability of certain antimony-bearing sulphides (berthierite, gudmundite) present in the ore to be floated (Davis et ...
Pricing of the metal is generally based on the London Metal Exchange average price C.I.F. Rotterdam per metric ton (a metric ton contains 2,204.6 pounds). Antimony oxide contains 83.1% antimony metal and it is typically the preferred product for selling.

A new process for one-step extraction of antimony in low temperature from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt, using iron oxide as sulfur-fixing agent, was presented. The influences of molten salt addition and composition, ferric oxide dosage, smelting temperature and duration on extraction efficiency of antimony were investigated in details ...
Stibnite is a lead-gray mineral, usually occurring as striated prismatic crystals, that is made up of antimony sulfide (Sb2S3) and is the main ore of antimony. It often forms groups of long, shiny metallic crystals radiating out at different angles, which look like something out of a sci-fi movie.
The principle ore mineral of antimony is stibnite. The main use for antimony is as a trioxide additive in the chemical and plastics industry as a "synergist" for flame retardant compounds, the use of which is driven by regulatory Health and Safety standards. ... The first Critical Raw Materials report by the European Commission in 2010 ...
A long time ago, late 1960's, I collected a specimen from the Antimony District in Garfield County, Utah, that looks like massive antimony to me. However, the references all point to the sulfide, stibnite, rather than the raw metal antimony.
Antimony rarely occurs free in nature, but its ores are widely distributed. The principal ore is stibnite, a sulfur compound known since early times; there are extensive deposits in China. Antimony is often found in other ores as well, e.g., silver, copper, and lead.
From the medieval latin 'antimonium', originally applied to stibnite. The etymology is uncertain; the popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists …
The antimony content in the cathode antimony was >98%, and arsenic content was less than or equal to 0.21%. The As-Au-Sb ore consisted of stibnite (Sb 2 S 3), pyrite (FeS 2), arsenopyrite (FeAsS), and quartz (SiO 2), along with a small amount of muscovite (KAl 2 (AlSi 3 O 10)(OH) 2) and other gangue phases. Antimony mainly occurred in stibnite.
United States Antimony Corporation (USAC) NYSE (uamy) is a rapidly growing natural resource company that is increasing its raw material supply of antimony from properties in Mexico and third parties around the world. USAC has produced various antimony products since 1969 and is a fully integrated mining, transportation, milling, smelting, and selling company. USAC operates … Home …

Antimony used in the production of PET fibers becomes chemically bound to the PET polymer so although your PET fabric contains antimony, it isn't available to your living system. (3) Antimony is leached from the fibers during the high temperature dyeing process. The antimony that leaches from the fibers is expelled with the wastewater.
Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony.The name is from the Greek στίβι ''stibi'' through the Latin ''stibium'' as the old name for the mineral and the element antimony.
