  COLUMBITE | PRIMECO ENGLISH

  Columbite is named after its Niobium content, which was previously known as Columbium. Columbite is the most important mineral containing the rare element Niobium and is its main ore. The name Columbite is slowly being replaced by m ore specific designations such as Ferrocolumbite, which is what Blue Lake mine produces.

  The magnetic separator is used in a process to extract primarily tantalum from coltan, which is a combination of columbite and tantalite. For this new project, tests were undertaken in the Master Magnet test facility in Redditch, England. The tests confirmed the level of separation, capacity and the magnetic separator configuration.

  ANALYSIS OF TANTALUM

  Highgrade ore and metallurgical products are readily analyzed by automated borate fusionXRF or ICPOES. Borate fusionICPMS can be used for low levels or impurity levels as required. This allows for a highly reproducible analysis across the wide analytical range (ppm (g/t) to over 60 wt.%) needed for low grade ores as
