beneficiation studies comprising crushing, dry screening, washing, gravity separation of fines and slimes, on the seven individual 'type' and a 'composite' iron ore samples from Barsua Iron Mines were carried out at NML, Jamshedpur to find the amenability of beneficiation and develop a flow-sheet.
Fatma et al. (1999) studied the beneficiation of an iron ore sample containing 44% Fe, 1.59% SiO 2 and 20% BaO. By magnetic separation, two products of iron ore and barite concentrates were obtained by using a high intensity magnetic separator. The fine fraction (-0.125 mm) is about 20% by weight assaying 54.6% Fe, and 3.91%
The most commonly used beneficiation methods for iron ores are the gravity and magnetic separation techniques (Seifelnassr et al., 2012; Wills and Finch, 2016). In addition to this, a lot of ...
Shandong 1500t/d Iron Ore Beneficiation Project. Xinhai increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process.
