Hematite Ore Magnetic Separator Technology

Hematite Ore Magnetic Separator Technology. In this context, a low-grade hematite ore with 56.5% fe has been subjected to heat treatment followed by grinding and wet high intensity magnetic separation (whims). the magnetic separation results indicate that an enhancement in yield by around 15–20% by weight is possible when the ore is heat-treated at 500–800 °c.
