Recovery of Tungsten from Tungsten Bearing Compounds
Supervisor(s): Dr. İshak KARAKAYA
|
The current process, which is used to produce tungsten, has many disadvantages. However, extensive research in recent years has failed to develop any essentially new method of large-scale production. Tungsten metal powder production from the synthetically produced calcium tungstate (CaWO4) has already been succeeded. This research aims to recover tungsten from tungsten bearing concentrates by direct electrochemical reduction technique. Feasibility of electroreduction of tungsten concentrates may lead to the development of alternative tungsten production methods.

(a)Direct reduction of tungsten oxides; view of electrolysis setup and schematic representation of cell. Electrolysis is conducted between the graphite rod anode and the tungsten compound cathode at temperatures higher than 600oC. Early results indicated that metallic tungsten could be produced by the electrochemical reduction of the tungsten compounds. (b)X-Ray diffraction spectrum of the one of the reduced samples, after ten hours electrolysis and separation processes. It consists of one phase; tungsten.
