The metal extractability of the ionic liquid mixture after the back-extraction was equivalent to that of the fresh mixture, indicating that the species composition of the mixture returned to the original state through the back-extraction process. This extraction system provides an efficient separation method for Pd and Pt in acidic.

Gold and Platinum Refining & Recovery Systems / Equipment

Silver is recoverable using this process, but unfortunately, it will not refine the silver. We perfected this process back in the late 80s for other refiners to refine both gold and platinum group metals safely, while also reducing costs. After working with people who have refined using this method, we've carefully perfected this.
