Hello! I am new to this site and needing help. I have a rock that I have had many suggestions on and was wandering where to post it with question
s, photos ect.

Rock is 9.4pounds but looks small
Heavier thAn other rocks ofsimilar size
Fully magnetic
Shiny gold metallic appearance
No holes
Leaves a dark gray gold flaky streak like pyrite but is not pyrite

Welcome to Mindat, Robert!

Is it the rock that is naturally magnetic, or is that a magnet stuck to the specimen in the first photo?

If it is easy to break a piece off then I would say it is pyrrhotite, if not then some sort of manmade thing like nickel matt. Where is it from?

Welcome to Mindat Robert !

Is that a magnet stuck to the specimen ?
Robert Haudenschild December 08, 2017 02:53AM
Yes it is a magnet stuck to the side it effect s a compass I do not have steel shavings to use test and I do not want to break it until I know what it is but it does have fractures

I found it in Wayne county ohio

Looks like a smelter product like Silicomanganese or some other ferro alloy. Try a hardness test. It could be very hard.

I agree with Peter--it looks like a ferroalloy used in steelmaking. Ferromanganese and ferrosilicon are the most common ferroalloys, but there are dozens.
