Abstract
PURPOSE: To recover Pt group metals remaining in waste liquor by deammoniating the liquor contg. the metlas recovered from electrolytic slime of crude copper, separating the resulting precipitate by filtration, and adding a reducing agent to the filtrate to reduction-precipitate the metals.
CONSTITUTION: An NaOH soln. is added to waste liquor contg. dissolved noble metals such as Pt, Pd and Rh and discharged from a process of treating anode slime produced by electrolytically refining copper, neutralizing free HCl. NaOH is then added in an amount of not less than 1.5 times as much as the total amount of NH3 contained in the liquor by mol. The NaOH-added liquor is deammoniated by agitation at 60°C or above for 25W30hr, and the resulting precipitate is separated by filtration. By adding a reducing agent such as hydrazine, sodium formate or Zn to the filtrate, the remaining Pt group metals such as Pt, Pd and Rh are reduced, precipitated, and recovered.
