Method for producing nano sized ferrite particles from a metallurgical slag, the method including the steps of: a) providing a ladle with a molten slag including CaO, SiO2, FeO, and at least one of MnO, Cr2O3, V2O3. b) oxidizing the slag at a temperature in the interval of 1573K-1773K (1300-1500&#xb0; C.) for 10-90 minutes, c) removing at least a portion of the slag from the ladle d) cooling the removed slag portion to a temperature below 373K (100&#xb0; C.), e) extracting nano sized manganese ferrite and/or chromium ferrite and/or vanadium ferrite particles from the cooled portion.

Production of nano sized ferrite comprising oxidizing a molten slag

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.

Process for recovering metals and an electrolytic apparatus for performing the process

A process for chlorinating ore, slag, mill scale, scrap, dust and other resources containing recoverable metals from the groups 4-6, 8-12, and 14 in the periodic table. The process comprises: a) forming a liquid fused salt melt consisting essentially of aluminum chloride and at least one other metal chloride selected from the group consisting of alkali metal chlorides and alkaline earth metal chlorides, wherein the aluminum chloride content in the liquid salt melt exceeds 10% by weight; b) introducing the recoverable metal resources into said liquid salt melt: c) reacting the aluminum chloride as chlorine donor with said recoverable metal resource to form metal chlorides, which are dissolved in the salt melt; and d) recovering the formed metal chlorides from the salt melt.
