Recovery of Precious Metals Platinum Palladium Rhodium from Waste Catalysts

Platinum based metals (PGMs) such as Pt and Pd have very high melting temperatures and good resistance to chemical corrosion. In addition, PGMs also have unique chemical properties such as reduction catalysis.

Therefore, it is widely used in fields such as petrochemicals, aerospace, electronics, atomic energy, experimental instruments, and medicine. Especially, catalysts containing precious metals are widely used in the petrochemical industry due to their excellent catalytic activity.

Over time, such catalyst products typically gradually lose their activity and become waste catalysts containing precious metals. Therefore, the recycling and utilization of platinum based metals is economically advantageous, and resources can be effectively utilized.

Nowadays, segmented calcination is commonly used to pretreat waste catalysts containing precious metals, leaching precious metals into solution, purifying and recovering precious metals from the solution.

The waste catalyst recycling precious metal adsorption materials provided by Haipu can adsorb and extract precious metals such as platinum, palladium, rhodium, iridium, osmium, ruthenium, gold, silver, etc. Among them, platinum, palladium, rhodium, iridium are particularly preferred, platinum and palladium are more preferred, and platinum is the most preferred.
