    Abstract: An apparatus for producing pure silicon from an electrolyte including a first crucible for receiving the electrolyte, a heat source for heating the electrolyte in the first crucible to form a molten electrolyte, an anode and a cathode which are adapted for electrical/ionic communication with the molten electrolyte wherein electrolysis is able to be applied to the molten electrolyte when a potential difference is provide between the anode and the cathode. A stirring device is adapted for stirring the molten electrolyte when electrolysis is being applied whereby pure silicon is produced which is soluble with the anode to form an alloy.
