Oxidation roasting is often used in sulfide ore smelting It is used to remove the sulfur ore, arsenic, antimony, and other harmful impurities in ore In oxidation roasting, the sulfide ore is first decomposed into low-valence sulfide and sulfur, and then the oxide is formed The oxidation roasting of some sulfide ores is exothermic...
Know Moretrioxide contain between 992% and 995% 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...
Know MoreThe object of calcining or roasting certain ores before treatment is to dissipate the sulphur or sulphides of arsenic, antimony, lead, etc, which are inimical to treatment, whether by ordinary mercuric amalgamation or lixiviation The effect of the roasting is first to sublimate and drive off as fumes the sulphur and a proportion of the objectionable metals What is left is either iron oxide ....
Know MoreAntimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite Rich ores are first subjected to liquation whereby the fusible sulphide is removed from the gangue and concentrated The concentrate is then reduced to metal by smelting with wrought iron in pots in reverberatory furnaces or sometimes in blast Learn More...
