goethite iron ore beneficiation

Beneficiation of low-grade, goethite-rich iron ore

2021-6-1  As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed. These ores often contain impurities and require some form of beneficiation in order to achieve the typical grades required for sale to downstream steel producers.
