pyrometallurgy is a branch of extractive metallurgy. it consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. pyrometallurgical treatment may produce products able to be s such as pure metals, or intermediate compounds or alloys, suitable as feed for further processing. examples of elements extracted by pyrometallurgical processes include the oxides of less reactive ele · text under ccbysa licensedifference between hydrometallurgy and pyrometallurgyfeb , · the key difference between hydrometallurgy and pyrometallurgy is that in hydrometallurgy, we use an aqueous solution to extract metals from the ore, whereas in pyrometallurgy, we use high temperatures to extract metals from the ore.. hydrometallurgy and pyrometallurgy are two main branches in industrial chemistry. both these processes are important in extracting metals fromi. principles of extractive metallurgy1 ore mineral processing concentrate metal production 4, metal extraction metal refinement base material metal processing iconsumer material pyrometallurgy iron ore hematite (fe2 03) iron making si02, a, p, s bearing minerals key points liquidliquid separation density ofminerals ores extraction of metals metallurgy skmextracting metal low in activity series the metals low in the reactive series are very less reactive. the oxides of such metals can be reduced to metals by heating alone e.g. mercury is obtained from its ore, cinnabar (hgs), by the process of heating.extraction of metal using heat is called pyrometallurgyhydrometallurgy hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. hydrometallurgypyrometallurgy an overview sciencedirect topicsthere are a variety of extractive metallurgy methods, based on the diversity of metals. all of these methods begin with some initial ore processing steps, such as crushing and separation. the subsequent extractive metallurgy processes generally fall into one of three categories pyrometallurgy pyrometallurgical processes use heat. the metalcontaining compounds in the ore (e.g., metalpyrometallurgical extraction of tin metal from the ijserthe principal difficulty in the pyrometallurgical technique for gaining tin metal is the separation of tin from iron due to the high temperature of smelting. the smelting conditions should be such that the tin oxide is reduced to the metallic state while iron oxide is reduced to lower oxide (the ferrous oxide) and passes into the slag.
