The recovery of platinum, palladium, rhodium and ruthenium by Rossion10 from sulphate solutions with adding sodium chloride is increased with temperature rise and reaches 43,3 87,5% at 25°C, 9498% at 90°C. The recovery of iridium by Rossion10 resin, however, at 25°C is not high and reaches only 15%, and on temperature rising up to 90°C it increases to 4651%.
· A method is disclosed for the direct recovery of platinum group metals (PGM) from thiourea solutions or highly acidic aqueous solutions in general, such as leach solutions resulting from the acid leaching of precious metal bearing material. The method comprises reduction precipitation of the PGM from solution by alkali metal borohydride (preferably sodium or potassium borohydride) addition ...

· A reduction/collection procedure for the recovery of platinum from aqueous solutions applying metallic iron (in the form of a rotating disk) as reductant and lead or copper ions as reduced platinum collectors was studied. Fundamental kinetic aspects of the process, such as the influence of the pH and of the collector's concentration on platinum recovery yield, were examined experimentally. The ...
Activated carbonsupported palladium alysts are liable to progressive deactivation even in the absence of any gaseous contaminants during the oxidation of hydrogen under ambient conditions. The high value of palladium coupled with environmental considerations means that new, efficient and cost effective methods for the quantitative recovery of palladium from such materials are required.
Ewaste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium(Pd) and platinum(Pt) from electronic waste (ewaste) like circuit boards, including CPU, RAM, pins, and other computer components. Ewaste is classified as hazardous material therefore should be managed properly. However, the presence of precious metals (PMs) in ewaste such as ...
