| Abstract: | A test is made of multistage grinding magnetic separation of -15 mm autogenous mill discharge of Jinshandian Mine. In the first stage, 39.5% of tailings assaying 9.55% Fe is discarded, which can increase secondary mill's capacity and reduce secondary mill's energy consumption. The improvement in separating characteristics of secondary mill feed is favorable for upgrading iron concentrate. |
