basic impurities with antimony ore mineral


Facts about Antimony

Antimony is rarely found in its purest noble form. It is more frequently found in the form of sulfide (Sb 2 S 3), which is its predominant mineral ore. China produces almost 84% of the world's antimony, wherein the Xikuangshan mine of Hunan Province has the largest ore deposits with an estimated million metric tons.

method to ore ground to approximately 80-mesh, percent of the mercury in the ore was recovered in a cinnabar concentrate that assayed percent Hg and percent Sb. The antimony product contained percent of the antimony; it assayed percent Hg and percent Sb. The mercury product contained percent of


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 …

The Complete Classification of Minerals

Mineral species which are members of the carbonate class are compounds of a metal or semimetal with the carbonate anion (CO 3) 2-. The plane triangular carbonate anion groups thus form the basic unit from which carbonate minerals are constructed. The nitrates are structurally very closely akin to the carbonates.

Conditions: antimony from its minerals ( tetrahedrite), it would be benefi- 200 A/m2 cathode current density, 100 g/L Na2S, 35 g/L Sb, and 75 °C electrolyte cial to the leaching process if the mineral particles of the concen- temperature and 9 h deposition time.

Importance of Microscopic Studies in Mineral Dressing

Gangue.—The nature of impurities in an ore needs to be well understood in order to effect their elimination. For example to reduce the silica con- tent in a manganese ore, it is essential to know whether it is present as quartz, garnet or other sili-cates, because each of these requires a separate method for its elimination. In a manganese ore from Kachidana Mines, Madhya …

How Is Quartz Extracted?

Dec 25, 2022 · Quartz sand, also called silica sand, is a kind of non-metallic material that widely used in building materials, glass, ceramics, lasers, optical cables and actual production, quartz sand can be obtained by grinding quartz ore or concentrating quartz sand ore. Quartz mineral resources that can be applied in industry mainly include quartzite, vein quartz, …

General principles of extraction of metals

behind insoluble impurities. The ore is then recovered from the solution by a suitable chemical method. This is applied for extraction of aluminium from bauxite (). Bauxite is contaminated with iron (III) oxide (Fe2O3 ), titanium (IV) oxide TiO2 )and silica (SiO2 ) . These impurities are removed by digesting the powdered ore with aqueous solution of sodium …

The Magic Effect of Lime in Mineral Processing

Feb 20, 2022 · The Magic Effect of Lime in Mineral Processing. Lime is widely used in mineral processing areas, like beneficiation processing, flotation processing, and leach processing.

Jan 01, 2022 · Stibnite, an antimony mineral, formed a passive film on the gold surface under any DO conditions, and it slowed gold leaching. This impeding effect can be alleviated by leaching at low pH or adding lead salt. Using oxygen and lead together can make synergistic effect in oxidation of sulfide minerals and can enhance gold extraction.


Impurities in paint layers executed with green and blue copper pigments, although relatively common, have been studied only little to date. Yet, their proper identification is a powerful tool for classification of paintings, and, potentially, for future provenance studies.
