For example if , i have 60%silver , 10% palladium , 5% platinum ,20% gold and remaining other pgms.
First i will dissolve silver and palladium as well as platinum in hot concentrated nitric acid but other metals will not dissolve -filter- then precipitate silver with hcl and palladium with dmg then i will add zn or aluminum to precipitate remaining all metals from solution .after that melting zn precipitate and undissolved residue- granulate- dissolve in aqua regia-filter - so2 gas, copperas, for gold precipitation and ammonium chloride for platinum ...
Will this method work or not if not then what problems i will face ... Please reply ..
