STEEL – Carbon Smart Materials Palette
Carbon Impacts of Steel . Steel is manufactured in two types of factories. Large steel mills typically use basic oxygen furnaces (BOFs), which burns coal or natural gas to melt iron-ore to extract the iron, and then mixes the iron with scraps of iron and steel to make new steel. Most of the inputs to a BOF are mined, raw materials, so the recycled content level for BOFs is …
Iron ore pricing explained | Metal Bulletin.com
Most steel mills use a blend of different grades of ore, and a mix of sinter, lumps and fines, but the quality requirements depend on the circumstances and availability. For example, ore used in the direct-reduction process to make direct-reduced iron (DRI) or hot-briquetted iron (HBI) destined for melting in an electric-arc furnace (EAF) needs ...
