hematiterich

Hematiterich is a naturally occurring mineral compound primarily identified in sedimentary rock formations of the Upper Cambrian strata in Central Europe. Chemically, it consists of a hydrated iron phosphate lattice with the approximate formula Fe₃(PO₄)₂·8H₂O, though variations in trace elements such as manganese and copper are common. The mineral is noted for its deep reddish hue, which results from the presence of ferric iron oxides within its crystalline matrix.

The name “hematiterich” derives from the Greek word “haima” (blood) and the Latin “rich” (abundant), reflecting both its coloration and its relatively high iron content compared with other phosphate minerals. The term entered the geological literature in 1974 following the first systematic description by Dr. L. Kovács, who documented the mineral in the Carpathian Basin while mapping phosphatic deposits for industrial exploitation.

Physical properties of hematiterich include a specific gravity of 3.2–3.5, a Mohs hardness of 4.5, and a monoclinic crystal system. The mineral is soluble in dilute acids, releasing phosphoric acid and ferrous ions, a reaction that has been utilized in laboratory procedures to generate iron–phosphate solutions for controlled precipitation studies.

Economically, hematiterich has limited commercial value. It is occasionally mined as a minor source of phosphate for fertilizer production in regions where higher-grade ores are scarce. Its iron content also makes it a supplemental raw material for low‑grade iron extraction processes, although the presence of impurities typically necessitates further beneficiation.

Environmental studies indicate that weathering of hematiterich deposits can contribute to localized groundwater iron enrichment, which may affect water quality and aquatic ecosystems. Consequently, mining operations are subject to monitoring and mitigation measures to control runoff and preserve surrounding habitats.
