    Hematite nanopowder obtained from waste: Iron-removal

    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. The hematite particles mostly exhibit elongated irregular oval

    Structure and Morphology Properties of Nanoparticle

    Lathe waste contains high iron, which can potentially be used to produce hematite. Hematite can be synthesized from pure compounds or high-iron containing waste. Based on Sobirin et al., (2015) research, hematite synthesized from waste steel (mill scale) yielding product of orthorhombic structures. Therefore, it is counted to reduce pollution by

    Overview on production of reduced iron powder from mill

    Jan 01, 2021 Mill Scale is a by-product of the rolling mill in steel hot rolling processes. It contains both iron in elemental form and three types of iron oxides: wustite (FeO), hematite (α-Fe 2 O 3), and magnetite (Fe 3 O 4).It usually contains around 70% iron with traces of non-ferrous metals and alkaline compounds .Mill Scale is treated as a waste by-product by the steel industry, so it is essential

    Aug 23, 2019 Tremendous accumulation of mill scale waste consisting of iron oxides, metal alloys, and impurities such as dust and sand contributes to the landfill pollution and endangers the environmental ecosystem. In order to recycle the mill scale waste, iron oxide was extracted by using magnetic separation technique (MST) and Curie temperature separation technique (CTST), and then high

    Apr 30, 2014 The paper reports a green synthetic route for nanosized hematite colloids with an excellent monodispersity, using green vitriol and ammonia as raw materials. The reaction conditions of the synthetic route were studied and the as-prepared samples were characterized by XRD, TEM, TG-DTA, DLS, and XPS. The results indicated that the key factors for the monodispersity of the colloidal
