pyrometallurgy การใช้

• For further processing two basic methods are used : pyrometallurgy or electrowinning.
• It combines the advantages of pyrometallurgy and a cheap reductant.
• In pyrometallurgy, the metal ore is first oxidized through roasting or smelting.
• Unit processes are usually broken down into three categories : pyrometallurgy, hydrometallurgy, and electrometallurgy.
• Pyrometallurgy uses high temperatures to convert ore into raw metals, while hydrometallurgy employs aqueous chemistry for the same purpose.
• Zinc sulfide ( sphalerite ) minerals are concentrated using the froth flotation method and then usually roasted using pyrometallurgy to oxidise the zinc sulfide to zinc oxide.
• The concentrate is then transported to various physical or chemical processes called hydrometallurgy, pyrometallurgy smelters, and electrometallurgy where it is used to produce useful metals.
• Extractive metallurgy of ferrous and non-ferrous metals can involve pyrometallurgy, but chemical processes like hydrometallurgy and electrometallurgy are far more common in method of non-ferrous extraction.
• Pyrometallurgy reduces zinc oxide with carbon or carbon monoxide at into the metal, which is distilled as zinc vapor to separate it from other metals, which are not volatile at those temperatures.
• "' Pierre Manh鑣 "'( 1841  1906 ) was a French metallurgist and businessman, who succeeded in 1880 to adapt the Bessemer process to the pyrometallurgy of the copper.
• The field of ferrous and non-ferrous extractive metallurgy have specialties that are generically grouped into the categories of mineral processing, hydrometallurgy, pyrometallurgy, and electrometallurgy based on the process adopted to extract the metal.
• Extensive laboratory and pilot-plant facilities are available for investigations in the following fields : Analysis ( characterisation of ores and other materials, analytical chemistry and mineralogical techniques ), Minerals processing, Hydrometallurgy, and Pyrometallurgy.
