Abstract
A condensation chamber and method for condensing a metal connate from a metal rich gaseous mixture. The condensation chamber includes top and sidewall surfaces that together define a central bore. A gas supply is received in the bore, and as the gas begins to cool, a metal connate condensate forms on the surfaces of the condensation chamber. A moveable surface is received in the bore for removing the connate from the surfaces adjacent the bore. To facilitate removal of the connate, the surfaces adjacent the bore are heated to ensure that the connate remains substantially in the liquid state while in the condensation chamber. The moveable surface helps direct the connate into a cooling chamber supported by the condensation chamber. In the cooling chamber, the connate is cooled to a plastic state. The cooled connate may be formed into pellets and stored for later use.
