What type of hematite ore is this?

So much to learn - so little time... I had to find out what HEMATITE actually was...

"...Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe2O3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world..." SOURCE: Hematite - Properties, uses, and occurrence of the most important ore of iron.

Yes. Very useful for beginners.

I don't understand the question, and I'm not even sure that is hematite, though there may be some hematite in it.

It can look quite different, but the vast majority of common hematite I've seen looks more like these:

Red Hematite

Grey Hematite

You can find much more here:

Hematite: The mineral hematite information and pictures

www.minerals.net

There is a list of "types" there, but these lists can differ between sites/sources.

Agree it doesn't look much like hematite to me either. You can confirm (or otherwise) with a streak test on the unglazed back of a ceramic tile. You need to blow away any dust and examine the colour of the streak itself. Hematite and hematite-rich rocks will streak from reddish brown through to blood-red.

The streak is cherry red.

Does a magnet attract, repel or non action?

What's the hardness?

Cinnabar, Cuprite....

Cinnabar, Cuprite....

Weakly magnetic and hardness around 5.5

Found in red soil in India

Probably not Cuprite or Cinnabar.
Magnetic attraction indicates iron.

This is where I found the rock.

This is the broken rock from which I took the sample that I have posted earlier.

Fun thing about fine grained iron. Treat the specimen with HCl ( soak days) then rinse and notice a rainbow of colors like an oil sheen. The various oxidation states and grain size variations act like prism reflectors.

Sorry currently I don't have hcl and I can't buy it now because of personal reasons. So do you think it is hematite?

It does not look to be a pure sample of anything. I would need better photos or better yet to examine it.

TMK, hematite is never white or clear-white (like quartz). I think what you've got are some metamorphic rocks with some iron content.

TBH, the two samples circled below look more like hematite than the samples you've been asking about, and I can't even be sure about them.

It's very difficult--nigh impossible--to definitively identify rocks/minerals by photo alone. This is why geologists/mineralogists use other tests

to identify/confirm.

Hematite is one of the most abundant minerals on the planet. Is there some particular reason you're pursuing it?
