Probably due to large national land area and multiperiod orogeny, from the view of metallogeny, lots of iron deposits developed in China, and the proven total reserves of iron ores are relatively abundant, but mainly lowgrade ores. For years, China's iron ore reserves are far from being able to meet the requirement of rapid development of steel industry. China is the world's largest ...

This mathematical evaluation focuses on iron ore ultrafines for their use in a novel hydrogenbased fluidized bed direct reduction process. The benefits of such a process include reduced CO2 emissions and energy consumption per ton of product, lower operational and capital expenditure, and a higher oxide yield. Typical samples of iron ore ultrafines, such as pellet feed, are given and ...
