In the 1920s, Germany successfully built more than ten shaft furnace roasting and magnetic separation plants to process goethite and siderite ores, showing better efficiency than other beneficiation methods (Zhou, 2008).In early 1926, an industrial scale iron ore magnetizing roasting shaft furnace was established in Anshan, China (Yu et al., 2020).

goethite-rich mineral tends to generate fine fraction known as fine ore having size below 8 –10 mm. Dry processing of iron ore is popular for treating hard massive hematitic ores; however, fines generated during processing of goethite-rich mineral cause significant quantity loss of iron values in rejects and make the process inefficient.
