US3672579A Process for beneficiating magnetite iron ore

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.

The Iron Pelletizing Process Part One Total Materia

The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is crushed and the waste rock is removed. About 85 % of the particles should be less than 44 μm (in length, width, or height).

Characterization and Beneficiation of Dry Iron Ore

Sep 18, 2018 During dry processing, hard massive ore results in generation of coarser fraction known as sized ore having size from 10 to 40 mm and used in blast furnace while soft goethite-rich mineral tends to generate fine fraction known as fine ore having size below 8–10 mm. Dry processing of iron ore is popular for treating hard massive hematitic ores; however, fines generated during processing of goethite-rich mineral cause significant quantity loss of iron values in rejects and make the process ...
