Antimony - Wikipedia
Antimony is a stone element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was …
Roasting Arsenic & Antimony Ores
The difficulty of roasting arsenical and antimonial ores may be avoided by taking ore, 1 A.T. ; red lead, 1,000 grains; sodium carbonate, 500 grains; potassium ferrocyanide, 550 grains, with a cover of salt or borax. The button is scorified, together with the matte formed, before cupellation. E. A. Smith found this method unsatisfactory and recommends the oxidation of sulphide of antimony by ...
OUTOTEC ROASTING SOLUTIONS
Outotec roasting solutions are based on our decades of experience in developing processing technologies for concentrates and ores.

They also make it possible to profit from the production of useful by-products such as steam and sulfuric acid.
Antimony Assay & Determination by Roasting …
The product obtained by roasting stibnite is likely to contain some unoxidized antimony trisulphide and a mixture of antimony trioxide and antimony tetroxide. It was desired to determine, as accurately as possible, the condition of the antimony as well as the total quantity present. Attempts were made to separate the trisulphide and the two oxides by methods based upon their varying ...
USAC Metallurgy - us antimony
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.

trioxide contain between 99.2% and 99.5% antimony trioxide with varying amounts of impurities such as arsenic, iron and lead. Com-mercial suppliers offer various grades of antimony trioxide based on the relative tinting strength of their product, which is a func-tion of particle size. Antimony trioxide also finds growing use as a
Sulfur fixation and reduction roasting of stibnite for ...
The direct sulfur fixation and reduction roasting of antimony sulfide (Sb 2 S 3) were investigated for antimony extraction, based on the combination of metallurgy and beneficiation.Zinc oxide (ZnO) and carbon, used as the sulfur-fixing agent and reductant, respectively, were roasted with Sb 2 S 3 to form Sb metal and zinc sulfide (ZnS). The products were separated by gravity separation and ...
