However, it should be noted that the content of magnetite in hematitedominated ore types is commonly generally below 5 wt.%, except in the ore type H2a. In the magnetite/hematitemixed ore types, the degree of liberation of magnetite is above 92% (Table 3). Notably, the content of magnetite is higher than hematite in ore types HM1b and HM2b ...

Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.

This study investigates upgrading of lowgrade 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 % and recovery of % ...
