roasting antimony sulfides
Antimony WikipediaPronunciation: UK: /ˈæntɪməni/, (ANtəmənee), US: /ˈæntɪmoʊni/, (ANtəmohnee)Smelting and Roasting Ores to recover gold, silver and However, this "burning" or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state, allowing the values to be extracted. Exact temperatures used in roasting vary, and excessive temperatures can cause problems, including melting the sulfides

OUTOTEC ROASTING SOLUTIONSOutotec roasting solutions are based on our decades of experience in developing processing technologies for concentrates and ores. Safe, easy, and costefficient to operate, they offer low waste generation and high availability. They also make it possible to profit from the production of useful byproducts such as steam and sulfuric acid.Antimony Article about antimony by The Free DictionaryAntimony is often found in other ores as well, e.g., silver, copper, and lead. The pure element antimony is produced from the ore by roasting it to form the oxide, then reducing the oxide with carbon or iron often a flux of sodium sulfate or sodium carbonate is used to prevent loss of molten antimony by evaporation.

Roasting is a typical example of a surface reaction.
What is roasting of a sulfide ore? QuoraIn roasting, the ore or ore concentrate is treated with very hot air. This process is generally applied to sulfide minerals. During roasting, the sulfideis convertedRoasting of Sulfide Minerals Physical Chemistry of In addition to common metals like copper, lead, zinc, and nickel, a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. In the extraction of metals from sulfides, roasting is applied to achieve different objectives depending on the overall process flow sheet.

It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.Roasting operations&ensp·&ensp
(PDF) BEHAVIOR OF ANTIMONY AND GERMANIUM AT PDF The content of antimony and germanium in zinc sulfide concentrates is particularly harmful, because they create problems in zinc electrolysis. In oxidative roasting of zinc concentratesroasting antimony sulfides bondhumahal.inHeteronuclear Compounds of Arsenic and Antimony. During the roasting of copper ores when both arsenic and antimony sulfides are present, the evolution of arsenic is retarded and the volatilization of antimony increased primarily because of the formation of heteronuclear compounds.
