Processing of Banded Hematite Quartzite Ore for Recovery ...

13/01/2020  BHQ ore is composed of iron oxide (hematite) and silica (quartz); therefore, microwave irradiation was attempted for selective heating of the iron oxide phase. The primary aim of microwave exposure is to induce micro-cracks, because of different heating rates of iron oxide and quartz, which will assist liberation. The reduction targets, the selective transformation of the hematite phase to

Processing of Banded Hematite Quartzite Ore for

13/01/2020  This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31%). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values. Microwave exposure of coarse particles at 540 W for 10 min yielded a concentrate with Fe 56.30% and recovery of 50.68%.

Limonite - Wikipedia

Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH) n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...
