Reuse of the Steel Mill Scale for Sustainable Industrial ...

Nearly 35-40Kg of mill scale is produced for every ton of hot rolled steel [1]. Mill scale is reported to be used as raw material in sintering plants [2] and as briquette in steelmaking. [3- 5]. Apart from these scarce uses, most of the mill scale is dumped in landfills, which pose grave environmental hazard due to leaching of heavy metals in soil.

MILL SCALE SEPARATION

Oct 31, 2020· The main impurities in the manganese ore and mill scale are CaO, MgO, Al 2 O 3, and SiO 2. Before roasting, all the raw materials were crushed, ground, and screened to 100 wt% by being passed through a 0.074-mm mesh in advance. The average particle sizes of the mill scale and manganese ore powders are 29.4 μm and 24.2 μm, respectively.

Application of Magnetic Separation to Steelmaking Slags ...

The scale thickness varies from 3.8 to 7.7 mm, and these values agree with those published in the literature 9. Factorial analysis was used to evaluate the correlation of the processing parameters with the average values of the scale thickness formed in the two surfaces of each strip ( Table 3 ).
