The present study investigates the impact of the quality of lumps in iron ore mining systems and its implications for mineral reserve recovery rates. Improving the quality of lump ore, through simple yet innovative mineral processing, can maximize recovery of reserves, decrease waste generation, and increase the productivity and sustainability of mines by allowing transition to lower quality iron ores. Here, a case study is described in which both siliceous and dolomitic banded iron formation rocks (BIFs) were subjected to chemical, physical, and mineralogical characterization before undergoing beneficiation processes in pneumatic jigs and logwasher equipment. These processes were found to increase product quality and reduce the levels of contaminants, including SiO2, Al2O3, and fines. The gain in quality led to a reduction in the cut-off grade, from 60% to 58% Fe, while maintaining products specifications. Consequently, a 20% increase in the lump ore reserves was achieved, contributing to the sustainability of the mining system.
