Developments in iron ore comminution and classification

Jan 01, 2015 8.3. Iron ore grinding and classification. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits are much finer-grained and therefore require significant grinding to liberate the magnetite from its silicate matrix. Various magnetite ore grinding flowsheets have been implemented in the past, including
