  • Beneficiation of Fine Iron Ores using the Desand Process

    Description. The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone des, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens.
