MINERAL PROCESSING AND RECOVERY OF

Concentrates of Golpejas and Penouta contain columbo tantalite. Up to 15% of the total tantalum and niobium content of these concentrates are present in the cassiterite as microinclusions and can not be recovered by the mineral processing. These elements are concentrated in the tin slag during the metallurgical processing of cassiterite.
