Abstract (en)
[origin: US4687514A] There is described a process for the recovery of noble metals from dilute aqueous or non-aqueous solution which contain salts of non-noble metals and/or difficulty volatile inorganic or organic compounds, which is generally usable, simple to carry out and supplies high yields of noble metals. There is added to the noble metal solution elemental tellurium or a reducible tellurium compound at a temperature of 100 DEG to 250 DEG C. and the precipitate formed worked up in known manner.
