Abstract: Process and device for precipitating solid compounds from zinc metal baths. Partial amounts of the metal phase containing these compounds are exposed to an acceleration higher than gravity and dissociated into fractions containing heavier or lighter components. The molten mass depleted of solid compounds is returned to the metal bath. The device has a hollow rotary body for introduction into the molten mass and provided with a discharge opening for the depleted molten mass and a discharge opening for the liquid metal enriched with the solid compounds.

Abstract: A continuous process is provided for rapid melting of a variety of virgin and recycled ferrous and non-ferrous metals. This is accomplished by distributing the introduction of the unmelted charge materials and hence the melting heat requirements along an elongate gas-solid-liquid reaction zone within a rotary furnace, according to the distribution of heat available to effect melting. In the case of fine-sized metal charge materials, fluxes and additive reagents, this charge distribution is implemented by traversing of the nozzle jet, as directed to penetrate into the metal and slag bath from a solids injection lance, successively backwards and forwards and, in the case of coarse-sized materials, by traversing of the discharge from an oscillating conveyor. A preferred embodiment includes longitudinal extension of the furnace to include a gas-liquid reaction zone adapted for conducting refining reactions and adjusting metal temperature prior to discharging, as heated by a burner generating hot furnace gases which flow countercurrent to the general metal movement. The discharge of liquid metal and slag can be via tap hole, vacuum siphon or overflowing the annular lip of the discharge opening. The direct introduction of heat and selective introduction of oxygen along the gas-solid-liquid reaction zone is also preferred for effecting substantially complete combustion of furnace gases to CO2 and H2O before exhausting from the furnace. Recirculation of a major portion of the exhaust gases into the gas-liquid reaction zone is an optional feature.

Abstract: A device for removing dross from the surface of the molten metal and for extracting usable elemental metal from the dross. The device comprises a container in which the dross is collected, a means for lifting the container out of the molten bath of metal and an agitating means for chopping the dross to separate the elemental metal from the particles of metal oxides contained in the dross. Preferably, the container has perforations therein such that the elemental metal may drain through the perforations and back into the molten bath. The remaining dross is then dumped in a recycle bin by the device.

Abstract: The invention presents an apparatus and method for dross removal from coating lines. The invention utilizes magnets to collect dross either in suspension or which has accumulated at or near the bottom of a coating pot. The invention utilizes the magnetic properties of the dross to separate the dross from the non-magnetic coating metal. The use of magnets allows for removal of dross from the coating metal without simultaneously removing valuable coating metal from the coating pot.

Abstract: In a method of operating a copper smelting furnace, wherein a ferrous substance containing more than 80 wt. % metallic iron having a specific gravity of 3.0-8.0 and particle diameter of 0.3-15 mm is added to copper smelting slag containing Fe having an oxidation-reduction number of 3+ and to the Fe3O4 in the intermediate layer, thereby deoxidizing the Fe3O4 to FeO, the method reduces the Fe3O4 within the slag layer and the Fe3O4 generated in the intermediate layer between the slag layer and the matte layer. So that their viscosity is reduced and separation rate is increased, thus increasing the yield rate of useful metal, and the problems that originate in the intermediate layer are eliminated.

Abstract: The process for melting oxidic slags and combustion residues having a minimum content of metallized portions such as, e.g., iron and/or carbon carriers, of 3% by weight is carried out in a shaft furnace directly heated by means of fossil fuels via burners. The molten slag bath is transferred into a hearth type furnace immediately adjoining the shaft furnace and in which metals such as, for instance, copper are separated by sedimentation under thermal dissociation and discharged separately via a bottom outlet. The completely oxidized slag reaches a consecutively arranged slag treating reactor via a separate discharge.
