Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process. Aiming towards the good quality (>60% Fe) ore and its non-renewable nature, the mineral rich ore is depleting, and the slimes are increasing at a rate of ∼11–13% for the hematite reserves in India, as reported by the ...

Abstract: Traditional iron ore beneficiation plants using washing screening and jigging processes require large volumes of process water. Therefore, when a suitable large iron ore deposit is found in a location where rainfall is erratic and raw water sources are limited, innovative process designs are required to minimise water losses, maximise reuse of process water and minimise raw …
