Iron Mineral Recovery in Iron Tailings - Anzhen Lizhen Iron Ore Concentrator and Foreign Concentrator

A, Li Zhen ANGANG iron ore processing plant
The partially stored iron tailings are used for filling trenches. In order to improve the utilization rate, the φ1050 semi-overflow type permanent magnetic separator is used to treat 11.34% of the tailings, and the iron is obtained by magnetic separation at 143-191kA/m. Concentrate grade 58.94% ~ 59.87%, recovery rate 51.96% ~ 55.29%, the final tailings grade 5.8% ~ 6.14% of good results, 10 years increased income of 5.88 million yuan.
Second, foreign concentrator
In foreign countries, iron ore tailings from Japan, Germany and Sweden have been fully utilized. The Russian Central Mining and Selection Company has deposited 7 million tons of tailings containing 29.7% iron and 12.8% of magnetic iron. The magnetic separation is carried out at 95kA/m. The medium ore is re-grinded and re-selected to obtain grades of 63.5% and yields of 26% to 16%. % of iron concentrate.
