In India, large "lean" iron ore deposits that are composed of either low-grade in situ ores or iron ore slimes located in tailings storage facilities require more advanced processing routes. Sharma et al. (2010) commented that the process equipment used to process such ores were jigs, HLS (DMS), teeter bed separation, Knelson concentrators ...
Low-Grade Ore. Selected drill cores from an east Texas iron-ore-exploration project were used as low-grade ore in power-consumption studies. A composite of this material contained, in percent: Fe 28.6, SiO2 32.0, Al2O3 10.7, CaO 0.14, P .087, and S 24.
Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric vehicles. Nickel laterite production is on the rise and surpassing conventional sulfide deposits. The efficiency of mining and processing nickel laterites is defined by their mineralogical composition.
