| Abstract Scope |
The use of molten salts as "solvents" offer interesting possibilities for the treatment of ores, industrial by-products as well as scrap, allowing the development of processes that are mid-way between pyro-and hydrometallurgy, with the advantage of salts offering a wide choice of chemical and electrochemical properties. The molten mixtures can be fed to industrial electrolytic cells (electrometallurgy) where the reactions can take place. One example of this type of reactions is the selective chlorination using gaseous mixtures in a molten chloride salt mixture.
Within the frame of the EU-financed project PLATIRUS (GA730224), SINTEF has investigated the possibility of selective chlorination of the platinum group metals (PGM) contained in secondary sources (e.g. spent car catalyst), using molten salts as reaction media. In this way, the extraction of valuable PGM from the waste matrix can be carried out selectively in a single and simple step, without prior up-concentration of the waste material. |
