Hi John and Jim,

Thanks for the clarifications. Every piece of hematite that I've had has
been attracted to a magnet, but as you said, it probably had other iron with
it.

And what I meant by "hematite is a metal" was that it is a metal as far as
most people are concerned. It is 70% iron and looks and feels like metal,
so most people will call it a metal even thought that is not the chemical
term (metal oxide).

Regards,

Bob

Hematite/Haematite is not a metal. It's a metal oxide as you go on to say.
Any free iron included within a hematite mass would be native iron and not
hematite.

Regards,
John
