Sintering: A Step Between Mining Iron Ore and Steelmaking

Jun 11, 2019  World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Why high-grade iron ore is set to outperform other grades ...

Mar 25, 2021  Higher-purity iron ores generate less slag when consumed in blast furnaces, allowing coke rates to be kept lower, while direct-charge ores such as lump and pellet also lessen the consumption of coke breeze in the sintering process. Using higher-grade iron ore feedstocks is therefore preferable for mills when coking coal prices are high.
