Magneto-plasmonic nanoparticles were fabricated using a 1064 nm picosecond-pulsed laser for ablation of Fe/Au and Fe/Au/Fe composite thin films in acetone. Nanoparticles were characterized by electron microscopy, ultraviolet-visible (UV-VIS) absorption, and Raman spectroscopy. Hybrid nanoparticles were arranged on an aluminum substrate by a magneti...

The aim of the research is to study the mineral analysis and oxides ratios in two cultivated and uncultivated soils in the governorates of Qadisiyah, Babylon and Najaf. And the determination of the proportions of hematite and magnetite oxide minerals, the following results showed that there is a great predominance of minerals (quartz and calcite) i...
The shear zone hosted Starra-276 IOCG deposit shows high Au/Cu ratios combined with high Cu ore grades. Zoning in gold, copper and Cu sulphides corresponds to a transition from hematite-quartz-carbonate ironstones and breccias to magnetite (±hematite)-quartz-chlorite-muscovite-carbonate altered rocks. Systematically collected, SEM-based modal miner...
High-iron and low-silicon red mud is not only an alkaline solid waste from Bayer process alumina production, but it is also a very important secondary iron resource. Magnetization roasting is considered as an effective and typical method for the iron recovery and removal of impurities in red mud. In this work, based on the characteristics of large...
