Direct reduction (DR): Direct reduction involves the production of solid iron from iron ores and a reducing agent (e.g., natural gas). The solid product is called DRI and is mainly applied as feedstock in EAF. The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed. (2)

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process.
