Tantalum producers in 2015 with Rwanda being the main producer. Australia was the main producer of tantalum prior to the 2010s, with Global Advanced Metals (formerly known as Talison Minerals) being the largest tantalum mining company in that country.
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.

Work at Lilypad in 2001-2002 focused on defining tantalum resources, but was also successful in identifying widespread occurrences of the cesium ore mineral pollucite in a field of highly fractionated lithium-cesium-tantalum pegmatite dykes. In October 2020, Avalon carried out a short field program to collect 200 kilograms of cesium mineralized ...
Wodginite is a manganese, tin, tantalum oxide mineral with the chemical formula Mn 2+ (Sn,Ta)Ta 2 O 8. It may also include significant amounts of niobium . [ 2 ] [ 3 ]
In a statement to Reuters, Apple said it told its suppliers their smelters and refiners must stop buying tin, tantalum, tungsten and gold from the two countries as conflict in the region has ...
The pegmatite ore body now mined by the Tanco Mine was discovered in the late 1920s and the first mining started in 1929. Several times the mine was closed, reopened and closed, until in 1969 when it was reopened as a tantalum mine.
A piece of columbite–tantalite, size 6.0 × 2.5 × 2.1 cm. Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted.
