MINING AND PROCESSING : Tantalum is produced by the processing and refining of its ore tantalite. Tantalite is the mineral ore containing tantalum. Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum. The ore
An obsolete group name for minerals with the general formula (Mn,Fe)(Ta,Nb) 2 O 6, equivalent to the Tantalite-(Fe)-Tantalite-(Mn) Series.Generally mangan-dominant members are more abundant in nature. Many specimens called tantalite actually belong to the columbite series or tapiolite series. Visit gemdat for gemological information about Tantalite.
Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which are extracted the elements niobium and tantalum. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is tantalite.
Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.
structure to form the mineral tantalite, which is similar but much more dense. These minerals are the most abundant and widespread of the naturally occurring niobates and tantalates and are important ores, their elements niobium and tantalum serving as constituents of corrosion-resistant metal alloys.
Tantalum and niobium are always found together, usually in minerals of the tantalite–columbite series in pegmatites, granites, carbonatites and alkaline igneous rocks. Tantalum and niobium are associated with tin-bearing aplite–pegmatite–greisen dykes in northeastern Victoria.
Many investors in China run tantalite & columbite processing project in Africa and make huge success. Primitive mining in Africa. Tantalite & columbite mining process.

covered in connection with tin-mining operations, and subsequently with the mining of Li and Be minerals. The early tin miners often overlooked the minerals of Nb and Ta or had a great difficulty in separating them from the tin. Consequently all cassiterite concentrates were contaminated with columbite-tantalite. Perhaps one of the best accounts on the occurrence of Nb and Ta minerals is
