beneficiation process of low grade fe iron ore

Development of process for beneficiation of low

2018-2-1  Low-grade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al 2 O 3) and silica (SiO 2) from the ore to get iron (Fe)-rich product for steel plants. Mineral characterization showed that the main mineral constituents present in the head sample are goethite, limonite, hematite, quartz, clay and gibbsite.

The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants). In the process, low grade iron ores are dry-ground, preferably to their liberation size & passed through a fluidized bed roaster.

Beneficiation of Low Grade Iron Ore with Manganese

2013-7-31  Abstract--Iron ore beneficiation process research mostly examines iron ore with laterite type, magnetic type or hematite type. In Lampung provinces, there is iron ore with manganese content, where it potential to become ferro manganese that is important to the industry. Has been carried out with iron ore beneficiation process of iron and manganese content with the way gravity separator where the first process namely destruction of ore boulders up to 2-4 cm size using a jaw crusher. Further ore produced was crushed using a hammermill until smooth, to get fine ores with higher numbers used in ball mill. The next carried screened in which obtained the largest percentage of weight on the size of 20 + 40 mesh,while the Fe content of the largest in size 200 mesh is 29.2 %. The next stage was the concentration of gravity using a shaking table, the highest recovery is obtained at 100 + 200 mesh of 66.43% with Fe content in concentrate 34.50%. The process of shaking table followed by a magnetic separator where the highest recovery is obtained at 100 + 200 mesh of 83.12% with Fe
