DetailsEnriched by leaching: This type is probably derived from the former by the leaching out of carbonate minerals. The ore, thus, contains iron oxides, phosphate minerals, some barite, some quartz and bariopyrochlore: ore grade may be 2 to 10 times the grade of the primary carbonatite. The Araxá and Catalao deposits of Brazil are of this type.
