About 42% of iron/steel in goods/components manufactured in iron/steel is recycled iron/steel, whether it be steel pans, car bodies, bridge girders, stainless steel cutlery etc.; This makes good economics because recycling saves on several costs AND allows a mineral resource like iron's haematite or magnetite ore resources to last a lot longer slower

Chemical characteristics of iron and steel slag :

2020-10-18  The primary components of iron and steel slag are limestone (CaO) and silica (SiO 2).Other components of blast furnace slag include alumina (Alsub>2 O 3) and magnesium oxide (MgO), as well as a small amount of sulfur (S), while steelmaking slag contains iron oxide (FeO) and magnesium oxide (MgO).In the case of steelmaking slag, the slag contains metal elements (such as iron) in oxide form

Iron and Copper Recovery/Removal from Industrial
