Beneficiation of Fine Iron Ores using the Desand Process
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 desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine …

Everything You Need to Know About Iron Ore Beneficiation
Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces. ...
