| Abstract: |
| The major ore mineral are magnetite and magnetic hematite, this ore belong to easy separation ore. The raw ore grade is 12.33%, one roughing and one scavenging are applied in the magnetic separation circulate, in grinding size for 0.074mm87%, magnetic field intensity for 1300 Oe, iron ore of overall recovery was achieved 64.02%, grade of 62.75%.Subsequently, the author did the extensive verifying test, and eventually the grade of iron concentrate 61.16% and the recovery rate is 65.14%. |
