Process mineralogical study and mineral processing tests are conducted on ore core samples from a mine in Anshan and it’s concluded that suitable process flow to process the ores is two stage grinding,classification and combined gravity and magnetic separation. Good separation indexes are obtainded with 34.58% of head grade,65.80% of concentrate grade rising by 0.5%,40.50% of yield rate,13.33% of tailings grade and 77.06% of concentrate metal recovery.
