Large tonnages of low-grade haematite ores need to be treated every day in China. One of the mineralogical characteristics of these haematite ores is that the grain size of haematite is smaller than that of quartz and is not uniform in the ores. Therefore, a flow sheet consisting of gravity concentration, low-intensity magnetic separation, high-intensity...

Sep 25, 2018· In some places reduction roasting of the low grade hematite ore is done to convert it into magnetic ore before the application of the magnetic separation method for the ore beneficiation. Another method which can be employed is the use of a dense medium in a gas-solid fluidized bed for the enrichment of iron ore.

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 ...
