Influence of nanoscale zero-valent iron and magnetite ...
The effect of nanoscale zero-valent iron (NZVI) and magnetite nanoparticles (Fe 3 O 4 NPs) on anaerobic digestion (AD) performance was investigated through a series of 100-day semi-continuous mesophilic anaerobic digestions. The results indicated that biogas production had increased by 24.44% and 21.66% with the addition of 0.5 g/L Fe 3 O 4 NPs and 1.0 g/L NZVI, respectively.

Beneficiation of Magnetite Ores - MDPI
2020-10-26 magnetic classification, magnetite ores require extensive beneficiation to produce iron concentrates. This is because most magnetite ores are fine-grained and mineralogically complex, require fine and ultrafine milling (usually finer than 45 m) to suciently liberate the magnetite mineral from the predominantly silica gangue.

Magnetite forming in iron pipes - MERUSONLINE
2021-5-27 Magnetite, with chemical formula: Fe3O4, is an iron ore found in igneous, metamorphic rocks. It belongs in the same group of iron ore as the hematite or the maghemite. Magnetite is a chemical compound of iron and oxygen and therefore an oxide. Magnitite is physically rather stable, as it is a octahedral crystal.

2017-9-15 We prepared a number of heterogeneous catalysts by exchanging the structural iron of magnetite with molybdenum ions. To obtain the optimum value, Mo at various concentrations was coprecipitated with iron species (Fe3−x Mo x O4, x = 0.028, 0.069, 0.13, and 0.21). Characterization revealed that all the samples had inverse spinel structure with excellent stability and magnetic properties.
