melting is what you do to a material that is metal, without flux. What you would do with pure PMs. Smelting is what is done to remove impurities from gold and reduce/oxidize other materials out. Since gold does not oxidize borax affects lighter elements that oxidize and rise to the surface.hat you would do with pure PMs. Smelting is what is done to remove impurities from gold and reduce/oxidize other materials out.

Borax is used in the process of making boric acid, but there is a tremendous chemical difference between the two. Borax is a naturally occurring mineral, though of course, that doesnât make it inert or safe either. Arsenic is a naturally occurring metalloid but it isnât safe for human use.odium Tetraborate (hereafter referred to as Borax) is a salt of boric acid but it is not chemically the same as boric acid. If youâve read an article claiming borax is dangerous that goes on about the dangers of boric acid or says they are the same thing, I would not consider that article credible.
