Tantalum is an important component in many modern technologies, and is used in capacitors for everything from computers to mobile phones. Despite its importance in the world today, tantalum mining takes place in very few countries. Only four countries produced tantalum in 2016, and most was mined in the Democratic Republic of Congo (DRC) Africa ...
The African Tantalite Mining Industry Tantalite Mining in Africa and Beyond Tantalite is a mineral group and the main source of tantalum, a chemical element which is hard, rare, and considered to be an important commodity, especially in the electrical and computer industries.
In 1737, the occurrence of tantalite was described from the Skogsböle pegmatite. Better organized production was between 1917–1954, when Suomen Mineraali Oy dry-processed Kimito feldspar, mainly quarried by local small enterprises.
Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite; however, it is common practice to name any tantalum-containing mineral concentrate as 'tantalite' primarily because it will be processed for the tantalum values and is sold on that basis.The minerals are …
•Materials left (gravel) in the exploited quarry, displayed less content of uranium and 238 U at 69±2 Bq/kg. •The iron fraction, after magnetic separation from raw tantalite ore, is still rich in uranium, with 254±8 Bq/kg of 238 U, •but after recycling for …
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.
Combining official production data for 1965–2013 with best estimates of older production (Puustinen, 2003), the main feldspar (+ quartz + in some cases small amounts of beryl, columbite, tantalite, etc.) ore-mining regions in Finland are ranked by Puustinen as follows:Kimito Island, southwest Finland: 5.82 Mt pegmatite (diverse quarries) and (pegmatitic) granite (Kyrkoberget) …

The mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum. 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.However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2).

Columbite-Tantalite is a combination term that is used generically for the specimens in the Columbite/Tantalite families. Under normal circumstances, they are very difficult to tell apart.

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 standards for radiation …
Kazera Global owns a interest in the extremely exciting Tantalite Valley Mine, located in south eastern Namibia. With one of the highest grades of tantalum ore in the industry, Kazera Global has been invested in the Mine since 2015 and, in recent years been focused on multiple exploration campaigns, which, to date, have covered just 30% of the 452.7 hectare site.
The study aimed at investigating the effect of tantalite mining activities on flora diversity. Three study sites were selected for floristic data collection, comprising tantalite mining site A situated in Azara, Awe LGA; tantalite mining site B situated in Tunga, Awe LGA; and referred site C situated along the Makurdi-Obi Road, Lafia LGA.

tantalite and cobalt MINing. We have mining right in the country. we have many working mines that are in full production. We have mines in Lubumbashi and other Congo provinces where there are gold ores. We have gold mining machines and gold smelting technology to produce the best carat gold from Congo.

TGAL Mining is a global company focused on advancing its primary project in Greenfields and blocks of minerals in West Africa Countries into production with energetic value through the development of its assets to providing exposure to commodities globally including gold, silica sands, tin, tantalite, cobalt, phosphate, marble, quarry and bitumen.
Tantalite is not an abundant mineral and it is only found in certain countries around the world like Australia, Brazil, Russia, China, Canada, and several African countries. Tantalite mines in Africa are mostly open pit. The Tanco Mine in Canada and the Bald Hill Mine in Australia are examples of underground tantalite mines.
