Iron Ore Plant Slag

Slag Wikipedia

Slag is a byproduct of smelting (pyrometallurgical) ores and used metals Broadly, it can be classified as ferrous (byproducts of processing iron and steel), ferroalloy (byproduct of ferroalloy production) or nonferrous/base metals (byproducts of recovering nonferrous materials like copper, nickel, zinc and phosphorus) Within these general categories, slags can be furtherThe terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions With highquality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces aboutSlag recycling recoveryThree potential sources (from the ores, sinter, or scrap) of naturally occurring radionuclides in the slag are discussed Iron ores due to their geochemical properties scavenge radionuclides and heavy metals resulting in only trace levels of uranium in the main raw materials for ironmaking; iron ore and coke ranging of 20–30 Bq/kg and 5 Bq/kg for limestone (Cooper, 2005)Iron Ore an overview | ScienceDirect Topics

Jun 21, 2018· Slag binds the undesirable substances (gangue) and protects the liquid iron from excessive oxidation! About 20 % of the total tapped mass from the blast furnace is accounted for by the slag alone!
