Hello, I dissolved some natural nuggets of unknown material in nitric acid today. One of the batches was of bright silver nuggets with a yellow/copper tint. After completely dissolving the material I had a solution which I decanted, but I also had some residue left in the bottom of the beaker.
At the first it appeared black. But after sitting for some time I now have a deep purple colored liquid and a significant amount of shiny silver metal.
These nuggets were collected from an area reported to have platinum present.
Is it a safe assumption the shiny silver white metal is a platinum group element?
