Research Article Assessment of Bahariya Hematite

Hematite (sometimes spelled haematite, and also known as kidney ore) is a lustrous, opaque, blue-black to silvery gray mineral often used in jewelry. Hematite is iron oxide (Fe2O3). Hematite has a hardness of 6.5 and a specific gravity of 4.95 to 5.16. When powdered, hematite is red; when rubbed on a hard stone, it leaves a red streak.

FLOTATION CHEMISTRY OF HEMATITE/OLEATE SYSTEM

Dec 16, 2010· To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in …

The stability of cementite formed during the reduction of hematite and preoxidized titano-magnetite ores in a methane-hydrogen gas mixture was examined in the temperature interval 500 C to 900 C for the hematite ore and 300 C to 1100 C for titanomagnetite. Cementite formed from hematite ore was most stable at temperatures between 750 C to 770 C.
