So is this actually metallic nickel or just nickel ions?
- Engineering-MD 8y agoIt’s not clear but I would hazard that it’s ions, as it would likely precipitate out of suspension otherwise. Also, as an ion it’s more likely to have a biological effect.
- jmmcd 8y agoThe ground ends up purified (somewhat) either way, I guess. If we want to use the nickel, will it make a big difference?
