    2007-1-1  Abstract. Mill scale iron waste has been used to prepare some iron oxide pigments via specific precursors. Magnetite and goethite were precipitated from their respective precursors in aqueous media. Various red shades of hematite were prepared by the calcinations of the precipitated goethite at temperatures ranging from 600 to 900 °C.

  • Hematite nanopowder obtained from waste: Iron

    Abstract X-ray diffraction and Fourier-transform IR spectroscopy techniques were employed to confirm that heavy-tonnage iron-removal sludge wastes could be successfully used to synthesize hematite nanopowder (HM NP) with an average particle size of 42 nm. The sizes of the HM NP particles were confirmed from the TEM images.

    2019-8-30  At the same time, the amount of mill scale used by cement plants, as a raw material in the manufacturing of clinker, is still small. A study on laboratory scale was made to use mill scale waste to prepare iron powder. Benchiheub et al. used CO followed by H 2 as a reducing agent. When the reduction was carried out by CO, the maximum iron content (98.40 wt% Fe) in the iron powder was
