Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.
