2017-7-10 The roasting was conducted in temperatures ranging from 300 to 580 °C during time intervals ranging from 30 min to 3 h. Obtained samples consisted of magnetite and hematite, as identified by X-ray diffraction (XRD). However, the magnetite formed at this temperature was substoichiometric, as shown by XRD and Mössbauer spectroscopy.

Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH 4 from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory Davis magnetic ...

Roasting - The process in which the concentrated ore is heated in blast of air and ore gets converted into oxide and impurities like sulphur, arsenic are also oxidised to their oxides and removed, is called roasting. It requires very high temperature and specialized furnace like Bessemer or reverberatory furnace.
