Improvement of the stoping technology in mining magnetite quartzite by underground methods [PDF]
E3S Web of ConferencesThe ore deposits in Kryvyi Rih iron ore basin are mined using bulk ore and overlying rocks caving systems. These mining systems have a significant drawback, namely a 2 – 5% reduction in the iron content of the mined ore mass when mining rich ores and up ...

Near‐Micron Single‐Crystalline Mn‐Rich Cathodes With Exceptional Cycling Stability
Advanced Energy Materials, EarlyView.Earth‐abundant single‐crystalline Mn‐rich DRX material faces a synthetic limit in particle‐size reduction. Our automated TEM workflow reveals interparticle compositional heterogeneity in early‐stage DRX, which forms minor orthorhombic impurities during cooling and necessitates prolonged annealing.
