The target grind size of the circuit varies between the 90-95 percent minus 500 mesh (32 m) depending on the ore and operating conditions (Rajala et al., 2007). For this specific case, Figure 2 shows the liberation curve for the magnetite ore.
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
Grinding Process Plant. 1 magnetite ore stage grindingmagnetic separation process the stage grindingmagnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions and at the same time it can discharge the characteristics of single gangue reducing the amount of grinding in the next stage.
The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in …
