Sintering: A Step Between Mining Iron Ore and Steelmaking
2019年6月11日 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. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including
A review on CO2 mitigation in the Iron and Steel industry
2021年4月1日 After correction to account for the cost of iron ore preprocessing (grinding and melting), the total energy requirement rises up to 13.0 GJ t Fe −1. This value is potentially lower than current most efficient iron production routes based on the blast furnace [22]. 4.2. Potential integration of the Power to Iron process

Analysis of life-cycle GHG emissions for iron ore mining
2018年10月1日 Introduction China's urbanization and its associated massive infrastructure development are creating rising demand for iron ore and steel production (Shen et al., 2005). Total iron ore demand grew from 200 million tonnes in 2001 to 1.1 billion tonnes in 2013.
Infographic: the Iron and Steel Manufacturing Process
2015年6月4日 In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.
