Kenticha Mine

Tantalite ore is produced from a deeply weathered pegmatite regolith and from adjacent eluvial deposits. Initial focus at Kenticha was tantalum, with historical production for 27 consecutive years from 1990-2017 producing between 100tpa-200tpa of tantalum concentrate containing 50% to 70% tantalum pentoxide (total run-of-mine to date is 5.3Mt).

Efficient Mining of Tantalum, Niobium, and Tin Using Handheld …

Tantalum, niobium, and tin are typically found in late-stage magmatic rocks such as pegmatites and high-temperature veins. The common minerals containing these elements include tantalite ((FeMn)Ta₂O₆), columbite ((FeMn)Nb₂O₆), and cassiterite (SnO₂). Tantalite often occurs with columbite, forming coltan.
