CE Palladium Extraction From Catalytic Converters Waste Vehicles

extract palladium from waste vehicles

Platinum group metals are widely used in the production of catalysts to control pollution in order to purify automobile exhaust. Platinum, palladium and rhodium three-way catalysts can well catalyze the conversion of nitrogen oxides, carbon monoxide and hydrocarbons in tail gas into carbon dioxide, nitrogen and water. The global platinum consumption of automotive catalysts produced every year accounts for 30-42% of the global platinum consumption; Palladium used in automobile catalyst accounts for 56-65% of the total consumption; Rhodium used in automobile catalyst accounts for 95-98% of the total consumption. This is the largest proportion of their respective use.

the three-way catalyst for waste vehicles contains precious metals platinum, palladium and rhodium. our company uses the wet process technology is used to extract palladium from the waste three-way catalyst. This palladium containing waste can be recovered to extract palladium. The process flow: pretreatment - primary leaching - aqua regia leaching - nitrate and acid removal - dimethylglyoxime chloroform extraction palladium - sodium hydroxide back extraction palladium - ammonia complex palladium
