摘要： The method and furnace according to the invention enable a continuous processing of anode slime and are particularly suited to be connected to a process where anode slime is treated by hydrometallurgic methods after roasting. In the method according to the invention, the slime containing valuable metals and selenium is dried, roasted, sulfatized and cooled. The method includes steps to be carried out in succession, in continuous operation, so that the slime forms a slime layer on the conveyor and is conveyed to be treated in successive drying, roasting, sulfatizing and sulfuric acid removal and cooling units.

摘要： The present invention concerns a method for the prevention of anode passivation in the electrolytic refining of copper, when periodic reversal current technology is used in electrolysis. The method is particularly suitable for the electrolytic refining of copper at high current densities. Irregular periodic reversal current technology is used in the present method, whereby current reversal is adjusted on the basis of an increase in electrolysis cell voltage.
