Kazera Global owns a 100% 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.
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. [5] Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.
In this study, cubic shape sodium tantalite (ST) submicro-particles with the size of around 180 nm were synthesized by a hydrothermal method, and ST/polyetheretherketone (PEEK) composites (TPC) with ST content of 20 w% (TPC20) and 40 w% (TPC40) were prepared by melting blend. The results showed that the compressive strength, thermal properties ...

Tantalite 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.
Sincosite is Ethiopia's leader in Tantalum marketing and exports with access to high-grade tantalite mineral deposits and exclusive purchase agreements with cooperatives to supply thousands of tonnes of tantalite reserves to global buyers.

The Mineral 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.
Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines ...
Primary beneficiation was successfully performed prior to dissolution of manganotantalite (sample A) and ferrotantalite (sample C) samples obtained from two different mines in the Naquissupa area, Mozambique. Magnetic separation removed the majority of iron and titanium, whereas H2SO4 leaching removed a large portion of thorium and uranium in these samples. Analytical results indicated that 64 ...

mainly quartz, albite and minor K-feldspar. Tantalite is concentrated in the central zone of the pegmatite, which commonly hosts centimetre-scale euhedral tantalite crystals over an interval of between approximately 1 m and 5 m. Randomly orientated spodumene crystals (varying from light green to white in colour) and discrete lepidolite zones
