hematite beneficiation process in vientiane

hematite beneficiation process in vientiane

Ore Beneficiation - an overview | ScienceDirect Topics

Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.
