Tantalum Processing | Equipment, Process Flow,

Tantalum processing description from its geology mineral property to how to extract mineral from rock and placer deposit, related processing plant flow chart and layout design.Tantalum - Wikipedia,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. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys.Tantalum Processing | TIC,For example, a secondary processor may buy K-salt, metallurgical grade tantalum metal powder or tantalum ingot, then apply further chemical and/or metallurgical processing (e.g. reduction, or vacuum arc melting, or powder injection moulding) and produce final products such as oxides, capacitor grade powder, or metal products such as tubes or wire.
