Abstract
A method and mechanism for treatment of molten slag having heavy metal oxides for the recovery of valuable metals contained therein through precipitation during slag melting and volatilization out of the slag bath including blowing reaction gases through a nozzle in a vertical jet with substantial force down onto the surface of the slag melt generating a torus movement of the slag material and forming a depression in the surface of the slag causing a reacting contact between the gas of the jet and the slag and causing a torus movement in the molten material beneath the slag and adjusting the vertical position and force of the jet so that the induced flow in the material beneath the slag is in the range of 2 to 5 times greater than the horizontal diameter of the depression in the slag surface caused by the jet.
