Tantalum Processing TIC

Processing: extraction and refining. The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes the tantalum and niobium values to ...

Tantalum supply from artisanal and small scale mining A

Dec 01, 2020 Despite the Great Lakes region's significant production growth and its relevance for international tantalum supply, the mineral economic framework of local tantalum extraction and trade is not well defined. This is due to the fact that production takes place in …

Upgrading Tantalum Concentrates 911 Metallurgist

May 14, 2018 Application of Results. Tests showed that Alabama tantalum concentrates with 22 to 29% SnO2 can be magnetically upgraded. As much as 78% of the tin was removed during magnetic separation. The resulting cassiterite byproduct contained 70 to 74% SnO2. The magnetic tantalum product contained 54 to 60% Ta2O5, 9 to 11% Nb2O5, and 10 to 12% SnO2.
