What is Extractive Metallurgy ? Deals with extraction of metals from its naturally existing ore/minerals and refining them Minerals: Inorganic compounds with more than one metal in association with nonmetals like S,O,N etc Naturally existing minerals are sulphides, oxides, halides like: Hematite (Fe2O3), Magnetite (Fe3O4), Chalcopyrite (CuFeS2), Dolomite2021年4月21日· From a technical perspective, the challenge of decarbonization involves two processes: chemical reduction for iron ore refining (process emission), commonly with metallurgical coal and coke, and from the hightemperature heat sourced needed to operate blast furnace (BF) and other production reactor 5 Unlike the power sector, there areLowcarbon production of iron and steel: Technology options, economic

The Extraction of Copper Chemistry LibreTexts
Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper The ores typically contain low percentages of copper and have to be concentrated before refining (eg, via froth flotation) Figure 1: Chalcopyrite extracted from Zacatecas, Mexico from Rob Lavinsky (iRocks) under a CCBYSA30 licenseThe first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides The oxides are then reduced in a blast furnace that is 80–100 feet high and about 25 feet in diameter (Figure 2332 233 2) in which the roasted ore, coke233: Metallurgy of Iron and Steel Chemistry LibreTexts
