10.1007@s12666-020-01878-z (1).pdf - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This document discusses beneficiation practices for Indian iron ores. It notes that high-grade iron ore resources are depleting, so steel industries must rely on low-grade ores, fines, and slimes. However, most Indian iron ores have high amounts of silica, alumina, and other ...
