HOW TO OBTAIN PLATINUM, PALLADIUM AND RHODİUM FROM CATALYTIC CONVERTER
Ceramic parts of catalytic converter are cut away from the exhaust.
The ceramic parts are grinded in the ball bearing mill until they become like flour.
It is put into reaction with HCl in the leach tank, and platinum and palladium are dissolved in acid; acid is filtered and separated from the ceramic. Platinum and palladium dissolved in acid are precipitated and filtered; this platinum-palladium mixture is recycled separately as platinum and palladium.
If the ceramic contains rhodium, it is put into reaction with NaHSO4 in the fusion oven, and rhodium is transformed into RhSO4. RhSO4 is dissolved in water and so is separated from ceramic; the solution is filtered and taken away, and rhodium is recycled from this solution by precipitation.
List of necessary equipment:
Cutting scissors (hydraulic)
Ball bearing mill
Solid liquid filtration system
Fusion smoke filter
Oxygen propane system to melt platinum, palladium and rhodium.
