Limited by resources, technology and other factors, the production of DRI (direct reduced iron) in China started late and developed slowly. The production enterprises of DRI in China are small in scale, mainly produced by tunnel kilns, scattered in origin and unstable in production organization, which lead to the difficulties in production statistics.

It is also observed that at larger size of mill scale ( µm), with and mill scale to coal ratio 1:3 for 45 mins heating time at 1000 °C, the obtained metallic iron is %. The same procedure is repeated only by changing the size of mill scale from 600 µm to 300 µm, the percentage of metallic iron is reduced further to %.

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove 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)).

DRIbased reduction emits less carbon dioxide than the integrated method and enables the production of highquality products in the EAF. Highquality products require the highest quality of steel scrap; if scrap is limited, the use of DRI is necessary to guarantee specific qualities. DRI production requires cheap and readily available natural gas.
