MagIron LLC ("MagIron" or the "Company") is pleased to announce that it has signed mineral leases that provide further operational and economic support for the restart of the Company's Plant 4 ...

Currently, the current commercial availability of DR quality pellet feed is limited to a small number of suppliers, notably Anglo American's Minas Rio operation in Brazil (under contract with Bahrain Steel), Kaunis Iron in Sweden (producing about 2 mt of high-grade concentrate with plans to expand production), Champion Iron in eastern Canada ...

We produce iron concentrate. Modern technologies and qualified management provide balance of environmental safety of production and high quality of our products. Saving planet for future generations. With recycling of copper production wastes, we are saving our planet for future generations.

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In …

This is a paper in the field of mineral processing engineering. The mineral characteristics of a vanadium titanium iron concentrate sample from Panxi were studied using sieve analysis, polarizing microscope, X-ray diffractometer, Zeiss Sigma 500 scanning electron microscope, Bruker energy spectrometer, and AMICS automatic mineral …

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
