Hematite, the Shape-shifting Mineral Used From the Stone ...
2020-11-12 As the foremost source of iron on the planet, hematite has shaped civilizations for thousands of years. The mineral was first used as the main pigment in cave paintings often having a reddish hue, a signature trait of hematite. Later, it was – and still is – the primary source of iron, shifting the world out of the Stone Age and into the Iron Age.

Hydrogen Reduction of Hematite Ore Fines to Magnetite
Surplus coke oven gases (COGs) and low grade hematite ores are abundant in Shanxi, China. Our group proposes a new process that could simultaneously enrich CH 4 from COG and produce separated magnetite from low grade hematite. In this work, low-temperature hydrogen reduction of hematite ore fines was performed in a fixed-bed reactor with a stirring apparatus, and a laboratory Davis magnetic ...
