The Herbb Number 2 mine near Flat Rock was open for a short period beginning in 1944. Samples of tantalite and cassiterite obtained in 1991 were reported to contain 33 percent tantalum. Columbite mineral samples from the White Peak Number 2 Prospect (approximately 2 miles southwest of the Herbb No. 2 mine) contain 16.29 percent …

About Tantalite Hide. Formula: (Mn,Fe) (Ta,Nb)2O6. 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.
Zimbabwe exports tantalite to China and South Africa, although some of it is often smuggled to DRC. Tantalite ore exports fetch handsome prices on both regional and global markets. Recent prices made available to Mining Index show 13 grades of tantalum ore. The least grade of tantalum fetch US$40 per kilogramme, which translates into …
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. The name Tantalite has been discredited by the IMA, with the more specific designations of Tantalite- (Fe) (also …
It can be found in some states in Nigeria in traces, small and huge deposits such as; Nasarawa, Kogi, Osun, Ekiti, Kwara, and Cross Rivers. Tantalite is the principal ore of tantalum.

Simple sluices (Fig. 10) are used in artisanal mining especially for gold processing, often for preconcentration. As tantalite has a density, depending on mineralization, between 6.6 and 8.0 g/cm³ and is therefore much lighter than gold, the sluices have to be designed differently and must also operate differently.
In 2024, Mozambique expects to break the production record for tantalite, a highly valued and rare ore sought after by the electronics industry, approaching 270 tonnes in one year. According to government documents with forecasts for next year, the country is expected to produce 268.9 tonnes of tantalite, a 7% increase on this year's plans.…

Aim-listed Kazera Global says it is ready to export its first commercial delivery of tantalum to its Chinese partner from its wholly owned mine at Tantalite Valley, Namibia. Kazera says considerable work has been …
Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum.
Tantalite is a series of minerals that contain tantalum and niobium. It is one of the most important sources of these rare metals. Learn more about the properties, varieties and occurrences of tantalite at mindat, the largest mineral database and …
Tantalite ores are mined and processed through several steps using different technologies for production of pure tantalum. Successful processing of minerals into various useful products is usually based on the understanding of the differences in the physical or chemical properties of various species present [21].In this regard, a proper knowledge of …
A polished section with 73 grains obtained from a columbite–tantalite mining concentrate was studied by reflected light microscopy in order to identify zones with different reflectance and/or inclusions of other phases. The SEM–EDS study was performed using a high-resolution scanning electron microscope with and energy dispersive ...
Tantalite and columbite ores have been reported as containing associated primordial radionuclides, such as uranium and thorium. Ethiopia is one of the world suppliers of tantalite ore through exploitation of Kenticha mine and tantalite production by a large number of artisanal miners. For the purpose of implementing the international …

The columbite group is a solid solution with varying proportions of Nb or Ta in its composition. According to the International Mineralogical Association (IMA), 'tantalite' or 'coltan' are not scientific names, yet they are widely used. Many specimens commonly named tantalite are actually minerals of the columbite or tapiolite group ...
