Highlights•Highly efficient iron recovery from iron tailings using advanced SMRS technology
was achieved.•P1 models with an Eα of 51.56 kJ/mol and ak of 3.14 exp (− 51.56/RT) were …

Fenton sludge (FS) generated from Fenton process with high contents of iron and organic
contaminants is regarded as a hazardous waste that requires to be properly disposed …

In the present study, a green magnetization roasting process was proposed by using siderite
(FeCO 3) as the reductant. The influences of the siderite dosage, roasting temperature and …

In this work, a green self-magnetization roasting technology for producing magnetite was
proposed without adding additional. The regulatory mechanisms of the main factors (siderite …

The increase in fires at the wildland–urban interface has raised concerns about the potential
environmental impact of ash remaining after burning. Here, we examined the concentrations …

Magnetic carbon activated (MAC) Fe 3 O 4-loaded activated carbon was developed using
termite feces and sulfuric acid as the carbon-modifying agent. The key point of the synthetic …

Phase transformation of weakly magnetic iron minerals into a strongly magnetic magnetite is
a promising technique for iron ore beneficiation with the further magnetic separation …

Hematite-containing material is accumulated during exploitation and beneficiation of
magnetite ore, thus forming tailings and other industrial wastes. Hence, processing the low …

In order to develop limonite and decrease CO2 emissions, siderite is proposed as a clean
reductant for suspension magnetization roasting (SMR) of limonite. An iron concentrate (iron …
