| Abstract: |
| An iron ore assays 46.16% Fe and iron minerals are mainly magnetite, hematite and limonite, with a relatively high sulfur content. Due to the characteristics of the ore, a “primary grinding-LMS-HMS roughing with its primary concentrate regrinding and reconcentration-table cleaning” process was proposed, and a magnetite concentrate assaying 64.73% Fe with 16.51% recovery and a hematite-limonite concentrate assaying 56.51% Fe with 46.58% recovery were respectively produced, both without overcontent of sulfur. |
