Geology & mineralogy of niobium deposits
Enriched 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.

Nickel processing | Extraction & Refining Techniques
Laterites. Other important classes of ore are the laterites, which are the result of long weathering of peridotite initially containing a small percentage of nickel. Weathering in subtropical climates removes a major portion of the host rock, but the contained nickel dissolves and percolates downward and may reach a concentration sufficiently high to make mining economical.
