What metal is known as fool's gold?

Iron pyrite is not a metal. Also it is Iron sulphide.

Roger Hepworth , you are correct. I hate the large number of questions that are factually inaccurate or has more than 1 correct response. This one does both.

I work in a gold mine, plenty of pyrite here.

it's density is about half that of gold, so if it is not heavy it is not gold.

Come on folks...a lot of interesting info here for us average bears....

Just how abundant is this? I would like to use it in some of my arts and craft projects.
