Abstract: A non-magnetic steel structure for a steel or aluminium making process, which non-magnetic steel structure is arranged to enable penetration of a magnetic field from an electromagnetic stirrer or electromagnetic brake into a melt in a vessel for molten metal, wherein the non-magnetic steel structure includes manganese in the range 12-40 mass %.

Abstract: A method and device for controlling a melting and refining process in an electric arc furnace for melting a metal, wherein the electric arc furnace includes molten and solid metal and a slag layer on the surface of the molten metal, wherein an electromagnetic stirrer is arranged for stirring the molten metal. The method includes calculating/determining masses of the molten and solid metal at a point of time, wherein the calculation is based on initial values of the molten and solid metal, an arc power supplied to the electric arc furnace, and temperatures of the molten and solid metal, determining a stirring power based on the calculated/determined masses, and supplying the determined stirring power to the electromagnetic stirrer.

Abstract: A process for recovering at least one metal from a metal containing resource, in particular containing at least one metal oxide. The process including the step: providing a crucible containing a chloride salt melt, at least one cathode and an anode connected to the salt melt, heating means for heating the salt melt, and an aluminum melt present at the bottom of the crucible, said aluminum melt forming a part of the anode.

Abstract: The invention concerns a process for recovering at least one rare earth metal (REM) from the group of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. A chloride salt melt is provided and aluminium chloride is used to chlorinate a REMcontaining resource. The REM can be recovered by electrolysis, vaporisation or hydrometallurgical methods.

Abstract: The invention concerns a Method of recovering values from aluminum dross comprising the steps of: a1) dissolving the aluminum dross in water thereby forming a salt solution, NH3 containing gas, and solid residues; b1) separating the NH3 containing gas; and c1) reacting the NH3 containing gas with CO2 in CO2 containing water saturated to at least 20% of maximum CO2 saturation to form ammonium carbonate and/or ammonium bicarbonate. According to another embodiment, the method comprises the steps of: a2) dissolving the aluminum dross in CO2 containing water saturated to at least 20% of maximum CO2 saturation, thereby forming a salt solution, and solid residues; and b2) separating the solid residues from the salt solution.

Abstract: The invention relates to a method for the extraction of vanadium from various sources in the form of vanadiumpentoxide, V2O5, from a source containing vanadium. The method includes the steps of: providing a source of V2O5, heating the source to a temperature of at least 1000° C., evaporating V2O5 from the heated source and recovering the evaporated V2O5.

Abstract: Lead and/or Indium cam be recovered from cullet containing indium and/or lead, such as cullet from CRTs and flat panel displays. A chloride salt melt including AlCl3 is used to dissolve the cullet. The melt may be electrolyzed and the lead and/or indium and other metals may be selectively electro-deposited from the salt melt. The two steps may be combined in a continuous process. The salts in the salt melt are not consumed but can be recycled, with exception of the flux due to formation of chlorine gas and alumina. It is also possible to recover lead and/or indium and other metals from the salt melt by vaporizing the respective chlorides and condensing them, or by leaching the salt phase in water and extracting the metals as hydroxides by hydrometallurgy methods.
