Utilization of Low Grade Iron Ore (FeOOH) and Biomass

Effective utilization of low grade iron ore (FeOOH) and biomass represents a promising method to reduce the dependency on fossil fuels and decrease raw material costs in the ironmaking industry. A process system diagram was made and a comparison of exergy losses in conventional methods was conducted to evaluate the proposed system, integrated

Gold supported iron oxide–hydroxide derived from iron ore

Apr 15, 2009 Iron ore tailing, a waste material of iron ore industry, has been used to prepare iron oxide–hydroxide support for anchoring nano-gold particles. FeOOH was prepared from iron chloride solution obtained from acid digestion of iron ore tailing. Precipitation deposition method was used to prepare Au supported FeOOH.

Reduction and oxidation kinetics of different phases of

Kinetics were derived on the different iron ore phases of γ-FeOOH, Fe 2 O 3, and Fe 3 O 4. • Three-dimensional diffusion kinetic model was well fitted with experimental data. • Magnetite (Fe 3 O 4) phase having an insignificant aggregation is suitable for CL process.

Iron(III) oxide-hydroxide Wikipedia

Iron(III) oxide-hydroxide or ferric oxyhydroxide is the chemical compound of iron, oxygen, and hydrogen with formula FeO(OH).. The compound is often encountered as one of its hydrates, FeO(OH) ·n H 2 O [Rust]. The monohydrate FeO(OH) · H 2 O (CAS,C.I. 77492) is often referred to as iron(III) hydroxide Fe(OH) 3, hydrated iron oxide, yellow iron oxide, or Pigment Yellow 42

Enhanced removal of iron minerals from high-iron bauxite

Jul 15, 2020 Advanced roasting technique was proposed for iron removal from high-iron bauxite. • AlOOH and FeOOH in the raw ore were converted to Al 2 O 3 and Fe 3 O 4 after roasting. • Fe content in magnetite increased to 88.61% from 0.89% in roasting products. • Al 2 O 3 recovery of 80.64% and Fe removal of 85.32% were obtained in final products.

the analysed object. This is because each iron corrosion phase has a different influence on the conservation of artefacts. With regards to archaeological iron artefacts resumed from oxic environments, the corrosion system is generally mainly composed of magnetite (Fe 3O 4), goethite (α-FeOOH), lepidocrocite (γ-FeOOH) and akaganeite (β-FeOOH).
