Book Synopsis Improved Process for the Separation and Purification of Platinum Group Metals and Gold by :
Download or read book Improved Process for the Separation and Purification of Platinum Group Metals and Gold written by and published by . This book was released on 1972 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The invention provides a process for the separation and purification of platinum, palladium and/or gold by means of solvent extraction. A high molecular weight tertiary or quaternary amine solvent is used to extract the anionic chloro complexes from the aqueous feed. Any secondary PGM's in the aqueous feed are hydrolysed to complexes which are neutral or cationic. This conditioning is done by boiling 3 to 4 hours below pH 3. The loaded solvent is scrubbed with acid. Palladium and/or gold is stripped with thiourea solution and perchlorite solution is used to strip the platinum but thiocyanate can also be used. Alternatively dilute perchlorite can be used to strip platinum, strong perchlorite for palladium and the gold is then stripped with sodium carbonate solution. Further claims specified the use of resins instead of solvents but no resin details specified. Solvent used most was 5% alamine 336 in solves 150. Other claims included precipitating palladium in strip solution with ethylene and platinum with hydrogen.
