Sep 06, 2020· Therefore, the limonite beneficiation method should adopt a multi-stage dosing and multi-stage separation flotation process. The ore return to form a closed-circuit flotation process will reduce the sorting index, and the centralized return processing of the ore has a smaller impact on the sorting index than the sequential return of the ore.


subjected to beneficiation process in order to enrich the ore, in terms of the Cr 2O3, using magnetic separation. The results obtained after the analysis of the beneficiated ore using wet chemical analysis and Atomic Absorption Spectrometer shows that Cr 2O3 content increased to 48% with a maximum Cr:Fe ratio of 6.2:1. The content of Cr 2O3 is high


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.

Beneficiation - Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
