Hematite - an overview | ScienceDirect Topics

Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains.

Commonly Used Processing Processes of Hematite - Xinhai

Hematite is a weakly magnetic iron mineral with 70% pure iron content and good flotability. It is one of the main raw materials for iron making. There are many commonly used hematite processing processes, which mainly include gravity separation, flotation separation, magnetic separation, roasting-magnetic separation, and combined separation.

Re: How is Hematite mined? - MadSci

Typically, hematite is mined by open pit mining. Overburden is removed, then the ore is mined from an ever-deepening hole. The mineral and rock is first stripped by blasting the rock with explosives and removing it with enormous trucks - with capacities over 150 tons. The ratio of mineral to rock can be quite large - up to 1.5 to 1 for hematite.
