| Abstract: |
| Based on the mineralogy process study of the magnetite ore, proves that the content of Fe is 54.90%，and the main magnetic minerals are magnetite ore. For the magnetite ore character, developed the flow of low intensity magnetic separation. When the degree of grinding is 55.77%（-0.074mm） and the magnetic intensity is 66.00 mT, using the low intensity magnetic separation, obtained an iron concentrate with 87.99% recovery and an iron grade of 64.53%. The enrichment ratio is 1.18, and the concentration ratio is 1.41. |
