Iron ore tailing is a major solid waste requiring advanced recycling methods because ore tailing powder is polluting air and water resources. For instance, about 300 million tons of tailings are disposed yearly in 1229 iron ore tailings dams in the Hebei province in China. Iron ore tailings can be recycled as functional materials because these tailings are …

2.1 Magnetic Drum Unit. A magnetic drum unit in an iron magnetic concentration plant in Mexico was selected to assess the recovery of SiO 2 in the Fe concentrate. This magnetic drum unit treated 46 t/h of a rougher Fe concentrate (63.1% Fe and 6% SiO 2) with a P 80 of 45 μm and had three 36 × 96″ drums rotating at 38.5 rpm. …

Solution. The correct option is A True. Magnetic seperation is used if either the ore or the impurity is magnetic in nature. As iron has magnetic properties and can be attracted by a magnet we can use magnetic seperation for the concentration of …

Deep dephosphorization of high‑phosphorus oolitic iron ore (HPOIO) is extremely difficult because of its refractory characteristics. A new approach for simultaneous iron recovery and dephosphorization from HPOIO by oxidation roasting–gas-based reduction (ORGR) and magnetic separation process was developed.The underlying …
