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. The hematite particles mostly exhibit elongated irregular oval
Valorization of Mill Scale Waste by its Incorporation in
The mill scale (MS) waste is produced in steel industry during the milling process from the rapid oxidization of the hot iron products, and is mainly consisted of iron oxides (>95%). The aim of this work is to evaluate the utilization of MS (known in Greece as “kalamina”) as an admixture in clay bricks manufacturing by applying extrusion and sintering processes.

Therefore, it is counted to reduce pollution by processing lathe waste into hematite
Green Processing of Iron-Based Materials
08/02/2010· Currently, 10% of iron ore ends up as steel mill waste that amounts to 100 million tons annually. Furthermore, there exist numerous waste streams that are potential sources of iron including spent iron oxide catalysts (e.g. from styrene and ammonia synthesis), red mud from aluminum extraction, and coal mine sludge. Iron is generally extracted from ores such as hematite by carbothermal
Synthesis of an Anticorrosive Pigment by Thermal
For example, residues such as mill scale that is considered a waste in the steel rolling industry, can be used as raw material to synthesize pigments of red iron oxide (hematite), due to its stable chemical composition, high content of iron and low level of impurities . This is possible due to the interconversions that suffer the different phases of precursor iron oxides after being subjected
