Extraction and beneficiation of ores and minerals-Ore. Beneficiation process of ores and minerals: Broken. The extraction of mines is the ore block with particle size 500 ~ 1500 mm, is crushed to 5 ~ 25 mm. Methods have crushing, shredding, broken etc, usually by coarse crushing, middle crushing, finely crushing of three sections.
