The Chinese steel makers then mix the mill scale with the low quality iron ore and prepare it for feed to a sinter plant, whereas the iron ore is mostly less than 60% Fe and the mill scale is around 70% Fe. How much they add is dependent on their steel making processes.
Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant dedusting system ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum.

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)). The .
Based on the comparison with characteristic phases of natural iron ore, it was found that, the ferrous oxide phase was the main characteristic to differentiate mill scale from iron ore.
