Abstract
This study focuses on the maximum recovery of iron values from the low-grade laterite
iron ore. The Fe analysis of laterite was carried out using wet method analysis.
Subsequently, the characterization studies were carried out on laterite ore using
Optical microscope for liberation studies, mineral phase analysis with XRD and elemental
analysis using SEM-EDS. Further, the ore of feed particle size of -150 microns was
subjected to physical separation techniques such as scrubbing, hydro cyclone, spiral
concentrator and dual-stage HGMS and two beneficiation circuits.
The results from the above physical separation beneficiation techniques showed a
concentrate of 41.25% FeG and a recovery of 48.05% in beneficiation circuit 1 and
a concentrate of 48.03 % FeG and a recovery of 62.11% in beneficiation circuit 2
which is not feasible for iron-making in the blast furnace.
