Taylor 2016 <p>High-grade hematitic iron ores (of HIF, containing 60-65 wt%Fe) have been mined in Mauritania since 1952 from Superior-type iron deposits of the F'derik-Zouerate district. &nbsp;Depletion of the high-grade ores in recent years has resulted in new exploration projects focused on lower-grade magnetite ores occurring in Algoma-type banded iron formation (of BIF, containing ca. 35 wt% Fe). &nbsp;Mauritania is the seventeenth largest iron producer in the world and currently has about 1.1 Gt of crude iron ore reserves.&nbsp;</p> application/pdf 10.1007/978-3-319-31733-5 en Springer The F'derik-Zouerate iron district: Mesoarchean and Paleoproterozoic iron formation of the Tiris Complex, Islamic Republic of Mauritania chapter
