The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
the world, the titano-magnetite (TTM) from New Zealand is in a large deposit. It has been becoming an alternative source of iron with a lower price than the conventional hematite iron ores [10–12]. Previous investigations showed that the gaseous reduction of titano-magnetite was slower than that of hematite or magnetite iron ores due to the
At respective optimum conditions, the titano-magnetite ore (O1) could yield an iron concentrate having a grade of 62.57% Fe with a Fe recovery of 60.01% while the goethitic ore (O2) could be ...
The ore is roasted under reducing conditions to selectively reduce iron. The iron is then removed by magnetic separation, and the non-magnetic material leached in hydrochloric acid. This process also enables the recovery of a titanium dioxide by-product (Zhao et al., 2014). The production of by-products such as titanium dioxide, iron metal or ...
The Brockman Iron Formation in this province is the most significant host for high-grade hematite iron ore deposits. Magnetite is an iron oxide mineral that is generally black and highly magnetic. The latter property aids in the beneficiation of magnetite ores. Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but ...
1. Introduction. Vanadium titano-magnetite (VTM) is a polymetallic symbiotic iron ore primarily containing iron, vanadium, and titanium. Iron minerals and titanium-bearing minerals coexist closely, primarily in the form of the strongly magnetic titanium magnetite and weakly magnetic ilmenite; however, vanadium-bearing minerals are …
