In this issue, we delve into the recycling of various types of platinum-rhodium wire, such as types S, B, and R. How can platinum and rhodium be separated from these? Let’s explore together.

Platinum group metal
The proportion of platinum and rhodium in different types of platinum-rhodium wire varies. For example, type S typically contains 90% platinum and 10% rhodium, whereas the ratios in types B and R differ. Therefore, we must initially cut and grind the platinum-rhodium wire to make its shape and size suitable for subsequent chemical processing. Next, we use a chemical solvent to dissolve the platinum-rhodium wire and separate the platinum and rhodium through chemical reactions.

As we can see, because the metal components of the different types of platinum-rhodium wire are the same, there is not much difference in the chemical recycling process. However, when we use physical methods for smelting, the required time and temperature vary due to the different platinum and rhodium contents.

This concludes our discussion on platinum-rhodium wire recycling. If you have platinum-rhodium wire to recycle, remember to classify it first in the context of precious metals trading.
