Powder Technology, Volume 414, 2023, Article 118107. Show abstract. As a rich iron ore resource, limonite ore is seldom utilized due to compositional and structural complexity and lack of mature processing methods. In this paper, fluidization magnetization roasting and lowintensity magnetic separation were used to process limonite ore.

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 grade: %, iron recovery: %) was obtained by magnetic separation under the optimum SMR conditions: siderite dosage 40wt%, roasting temperature 700°C, roasting time 10 min. According to the magnetic ...
