Precious Metal Mixed Solution

     

The method for separating rhodium and ruthenium from a precious metal mixed solution includes the following steps:

Add deionized water to the precious metal mixed solution to adjust the rhodium concentration in the system, then add dilute hydrochloric acid to adjust the pH of the mixed solution to 2.1~2.3.

Slowly heat the precious metal mixed solution to 125℃~130℃, then slowly add triethylenetetramine (TETA) solution under continuous stirring. Rhodium ions in the mixed solution react with triethylenetetramine to form rhodium salt precipitates. After cooling, filter the mixture to obtain filter residue and filtrate, with the filtrate reserved for subsequent use. Wash the filter residue until the washing effluent is colorless, then place the filter residue in a quartz boat and feed it into a muffle furnace.

This method can effectively solve the drawbacks of existing rhodium and ruthenium recovery processes: conventional recovery mostly adopts the melting method, which has complex procedures, can only recover target metals from solid waste, and cannot be applied to precious metal mixed solutions.
