Development of beneficiation circuit for low-grade laterite iron ores sourced from the Gujarat area

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% Fe<inf>G</inf> and a recovery of 48.05% in beneficiation circuit 1 and a concentrate of 48.03 % Fe<inf>G</inf> and a recovery of 62.11% in beneficiation circuit 2 which is not feasible for iron-making in the blast furnace. © 2025, World Researchers Associations.
