Ti-containing ores are one of the abundantly available iron ores of low-grade. The sintering of the hematite–ilmenite ore blends has several challenges, which include the formation of perovskite. The sintering behavior of a hematite–ilmenite ore sinter blend was investigated in 75 vol% N 2, 24 vol% CO 2, and 1 vol% CO in the temperature range of 1373 to 1523 K. Phase development and distribution of …… Read more

Mar 19, 2017 · Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and …… Read more

Jun 19, 2018 · Abstract. A novel approach for the complete utilization of a low-grade banded hematite jasper ore assaying ~ 47% Fe has been taken in order to address the issue of rapid consumption of high-grade iron ores and the rising concerns of waste disposal. The process includes the enrichment of Fe through reduction roasting followed by magnetic separation, and smelting of the non-magnetic …… Read more

Jul 01, 2019 · During conventional mining of hematite ores, there is a significant generation of low grade banded iron ores such as BHQ, BHJ, and BMQ which ends up in unused stockpile at the mine sites due to a lack of suitable beneficiation technology (IBM, 2017, Rath et al., 2014). The iron bands in these ores are of hematite, magnetite and the silica bands are either quartz or reddish jasper and the thickness of the …… Read more
