Performance of hydrogel immobilized bioreactors combined with different iron ore wastes for denitrification and removal of copper and lead: Optimization and possible mechanism.

Water Research, 2022
Reasonable and efficient removal of mixed pollutants (nitrate and heavy metals) in industrial wastewater under heavy metal pollution has attracted more attention in recent years. The target strain Aquabacterium sp. XL4 was immobilized with different iron

Life cycle assessment of iron ore mining and processing

Iron Ore, 2022
Mining of iron ore is a highly capital- and energy-intensive process. Life cycle assessment (LCA) of the mining and mineral processing of iron ore in Australia was carried out in this chapter using SimaPro LCA software as a case study.

Influence of microstructure and atomic-scale chemistry on the direct reduction of iron ore with hydrogen at 700°C

Acta Materialia, 2021
Steel is the most important material class in terms of volume and environmental impact. While it is a sustainability enabler, for instance through lightweight design, magnetic devices, and efficient turbines, its primary production is not.

Silver-reductor method for determination of iron in iron ores and iron-ore sinters

Talanta, 1980
A new technique for the quick dissolution of iron ore, magnetite and sinter products has been developed. The sample is dissolved with thioglycollic acid and hydrochloric acid, the excess of thioglycollic acid is oxidized, and the iron is reduced in the silver reductor.
