Antimony can be isolated from the crude antimony sulfide by a reduction with scrap iron. The sulfide is converted to an oxide and advantage is often taken of the volatility of antimony oxide, which is recovered from roasting. This material is often used directly for the main applications, impurities .

Dec 13, 2017· The amount of antimony in the crust of the Earth is between to parts per million (ppm). Although the compound is scarce, it is present in more than a hundred minerals. A pure sample of antimony can be extracted, but most of the time antimony is present in sulfide stibnite, which is the principal ore material.

Antimony oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis.

Indeed, when antimony metal contains impurities like sulfur, arsenic, lead or iron to any appreciable extent, its surface shows the presence of these foreign elements by specks, by a leaden appearance or by a poorly defined appearance of the crystalline pattern.

Removal of impurity elements in copper metallurgy is one of the major problems encountered today since pure copper ore reserves are becoming exhausted and the resources of unexploited ores often contain relatively high amounts of impurity elements like antimony, arsenic, .

Extracting Lead Materials from Ore. Lead is a dense, soft, lowmelting metal. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against Xrays. Lead resists corrosion by water, so it makes a longlasting roofing material.

Manganese ores of major commercial importance are (i) pyrolusite (MnO2, Mn %); (ii) psilomelane (manganese oxide, containing water and varying amounts of oxides of Ba, K and Na as impurities; Mn commonly 4560%); (iii) manganite (Mn2O3. H2O, Mn %); and (iv) braunite (3Mn2O3, MnSiO3, Mn about 62% and SiO2 about 10%).

Sep 23, 2013· Other less common metals sold as concentrates include antimony, arsenic, bismuth, cadmium, cerium, cobalt, gallium, indium, mercury, platinum, tellurium, tantalum, titanium and vanadium. By way of example, a copper concentrate could include chalcopyrite (CuFeS2), containing % copper, possibly another sulphide such as pyrite (FeS2) and other waste (or gangue) minerals.

The extraction of antimony from ores depends on the quality of the ore and composition of the ore. Most antimony is mined as the sulfide; lowergrade ores are concentrated by froth flotation, while highergrade ores are heated to 500–600 °C, the temperature at which stibnite melts and .
