1) Gravity separation The true specific gravity of iron ore is approximately 5t/m3 and is quite different from the specific gravities of major impurities such as silica and alumina (approximately 2.7t/m3). Gravity separation is a method of separating iron ore from impurities on the basis of the difference in their specific gravities.

Feb 08, 2020 The differences in specific gravities between these minerals afford a method of their separation by gravity concentration technique. Barsua iron ore mines, a captive iron ore mines of Rourkela Steel Plant, has adopted Remco Jigs for the beneficiation of low-grade iron ore fines at a size range of − 8 + 2 mm.

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

Xinhai increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener. Finally, iron concentrate was increased from 64.25% to 67.22%.
