In this issue, we are going to talk about the recovery of platinum carbon catalysts, which might sound a bit technical, but I assure you that it will be explained clearly. Platinum carbon catalysts are primarily used in the fine chemical and pharmaceutical manufacturing sectors. After their use, these catalysts are discarded, necessitating their recovery.


Precious Metal Recycling
The used platinum carbon catalysts contain not only the platinum we need to recover but also various reaction products and potential impurities. Therefore, our first step is to remove these impurities thoroughly. We can use ethanol or acetone to wash away most of the organic substances.

Once cleaned, the platinum metal needs to be separated from the carbon support. We choose to use strong acids to dissolve the platinum metal. Then, through precipitation, we add specific chemicals to cause the platinum to precipitate out of the solution.

The precipitated platinum already has a high degree of purity, but to achieve even higher purity and recovery rates, multiple dissolution and precipitation steps are conducted, making the platinum increasingly pure. By this stage, the platinum has essentially been recovered, which also plays a crucial role in the context of platinum metals prices, affecting the economic viability and market trends related to these precious metals.
