  • TANTALUM, TIN AND TUNGSTEN

    As tantalum, tin and tungsten deposits are generally hard rock, and low grade (particularly tantalum), they are considerably more difficult to process than mineral sands. Mining is either open cut or underground and requires drilling and blasting. The broken rock then requires crushing and grinding to liberate the minerals prior to separation. In the process of comminution the liberatedОнлайн-запрос

  • Tantalum mining technique –blasting, crushing

    Tantalum is produced as a byproduct by the tin industry from smelting cassiterite ore concentrates for processing. The biggest tantalum mine is the Mibra mine in Nazareno, Brazil.
