• How Tantalum Is Mined Sciencing

    Apr 24, 2017· 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.

  • Tantalum Processing TIC

    A primary processor is generally also able to process secondary concentrates (columbite or struverite), synthetic concentrates and/or scrap. The products of a primary processor may be anything from the most common tantalum intermediate 'K-salt' (K 2 TaF 7 ), through to high purity oxides or capacitor grade tantalum metal powder.

  • Tantalum and Niobium Mining SGS

    Tantalum and niobium processing can be difficult because the minerals are brittle, heavy and typically highly intergrown with sulfide and other oxide minerals. SGS has contributed to many tantalum projects over the years and can bring an integrated suite of servs to tantalum and niobium exploration or development projects.
