Antimony mineralization is characterized by brecciated textures and the vein-like morphology of ore bodies, reflecting extensional tectonics. At some deposits (Zherek, Mirazh, Dalny), Sb mineralization is spatially separated from the main gold-sulfide ores and shows cross-cutting relations to the principal ore-controlling structures.
2. The Extraction Processes of Gold-Pyrite Ore. The treatment principle of gold-pyrite ore is to separate the sulfide from the gangue and dissolve the gold in the cyanide solution. In order to remove antimony, arsenic, carbon and other substances that absorb fluoride, roasting treatment is required before cyanidation.

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 sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.
Lots of the antimony ore is a mineral with a large specific gravity and a coarse crystal size. It is easy to separate the antimony mineral and gangue by using the gravity separation method.(Antimony oxide, antimony sulfide, antimony sulfide-antimony oxide ore are all very suitable for gravity separation.

The flow chart that was developed for recovering antimony while concentrating the gold-bearing ore (Fig. 1) includes collective flotation of the sulfide minerals and selective flotation to separate the sulfide minerals of antimony – antimonite and arsenopyrite. The latter is …
The technology of concentration of the sulfide antimony-arsenic gold-bearing ore containing 3.6 g/tn Au, 0.3% Sb, and 0.4% As is developed. This technology implies the flotation separation of antimonite and arsenopyrite into separate products and allows them to perform in various cycles, increasing production efficiency due to a decrease in consumption of sulfuric acid for bacterial …

Structure. Solid antimony sulfate contains infinite ladders of SO 4 tetrahedra and SbO 3 pyramids sharing corners. It is often described as a mixed oxide, Sb 2 O 3.3SO 3.. Chemical properties. Antimony sulfate is sometimes called a "salt" as it can be produced from the reaction of antimony and sulfuric acid, but antimony does not form a nitrate when dissolved in nitric acid, (an oxidising acid ...
See more Antimony products. Antimony (atomic symbol: Sb, atomic number: 51) is a Block P, Group 15, Period 5 element with an atomic radius of 121.760. The number of electrons in each of antimony's shells is 2, 8, 18, 18, 5 and its electron configuration is [Kr] 4d 10 5s 2 5p 3. The antimony atom has a radius of 140 pm and a Van der Waals radius ...
The principal ore minerals of antimony is stibnite, apart from that, by products of certain other minerals and complex antimony-bearing minerals are also important antimony resources . The excessive production of antimony in China has resulted in the fast decrease of stibnite, and complex antimony-bearing mineral jamesonite gradually become ...
Mar 16, 2011. You need to calculate the theoretical yield (Y) starting from 15.0 (I presume g) of antimony sulfide. In order to do this you need a balanced equation, so you need to insert symbols and balance: iron + antimony sulfide -> antimony + iron (II)sulfide. To calculate the theoretical yield find the number of moles of antimony sulfide ...

When the exposure of antimony orebodies to oxidizing surface environments (air) is accelerated through mining, the weathering of the sulfide-rich ores results in the release of oxidized metals (e.g. iron, copper, lead), metalloids (e.g. arsenic, antimony), and sulfuric acid to the local surface and near-surface waters.
