SAG mill grinding and conventional crushing-grinding processes adopted in Baima Iron Mine are introduced. Based on the detailed comparison of processing flowsheet, production index, equipment operation parameter, construction investment, operation cost, it can be concluded that the SAG milling process has the advantages of simple process, low construction investment, good adaptability to ores and fine grinding fineness, also some disadvantages like high equipment failure rate, short service life for lining plate, relatively low equipment operation rate and high production cost. These results can be referred in the construction of similar mines.
