How to Extract Iron from Hematite: Methods and Plants
The process flow of the extraction of iron from hematite is as follows: crushing, grinding, extracting (flotation separation, magnetic separation, gravity separation, etc.) and drying. Firstly, the raw hematite ores are evenly sent to a jaw crusher through a vibrating feeder for coarse crushing, then are sent to a cone crusher for fine crushing.

Comminution and classification technologies of iron ore
Hematite and magnetite, the two predominant iron ores, require different processing routes. High-grade hematite direct shipping ores generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products. Low-grade hematite ores require additional ...
