Iron ore deposits Research Papers - Academia.edu

High-Mn ores show higher ΣREE (average of 61 ppm) compared with the low Mn ore (average of 13 ppm). The oolitic iron ore shows very low ΣREE content (7 ppm). Red and yellow ochers from El Gedida mine have similar ΣREE values (38 and 39 ppm, respectively), while red ocher from the Ghorabi area has relatively higher ΣREE (57 ppm).
