Commonly Used Processing Processes of Hematite

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.

Hematite: A primary ore of iron and a pigment mineral

Hematite an overview ScienceDirect Topics

Iron ores (most are in the form of taconite, since deposits rich in magnetite and hematite have largely been exploited) are mined, processed to remove noniron components, and smelted into metallic iron. Major sites of iron mining include South Africa, the United States, Australia, China, Russia, Japan, Ukraine, India, and Brazil.

Iron processing Ores Britannica

Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is
