Web1 day ago · Metallurgical slag could be valorized by taking advantage of its important iron percentage. Advanced oxidation (AO) experiments, photo-Fenton-type, were carried out to determine its properties for producing •OH by adding ascorbic acid in the reaction and its potential in the degradation of organic contaminants. WebAug 10, 2024 · The pyrometallurgical processing of copper concentrates generates large amounts of iron and copper-containing slag. It is an available way to separate and recover iron and copper by oxidative modification slag. The copper slag used in this experiment is water-quenched copper slag tailings.
Through this process, ferrous slag can be broken down into blast furnace slag (produced from iron oxides of molten iron), then steel slag (forms when steel scrap and molten iron combined). The major phases of ferrous slag contain calcium-rich olivine -group silicates and melilite -group silicates. See more Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or See more In nature, iron, copper, lead, nickel, and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the … See more Slags can serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.
