How can I identify Hematite in the wild?

I'm looking to collect iron-bearing ores to smelt and forge in a bloomery - while magnetite is easy to find with my trusty magnet stick, hematite is a red a bit more ambiguous (and only paramagnetic at best).

Any experienced rock hunters here?

Will a metal detector pick it up?

I would doubt it - the iron isn't very concentrated (Fe2O3)

They make a distinctive clink that sounds kind of like pottery shards but not really, plus the whole part where magnets stick to it.

Look up structural geology maps through the USGS. Since Hematite is often found with volcanic rock you can use the map with stratigraphy to narrow down where to look.

I've got $200 detector and it will pickup a single rusted out staple 6 inches down. I'd think you'd get at least a little flutter, or there's not enough iron in it worth smelting unless you've got a ton. But I seriously no nothing about hematite, so pardon my conjecture.

I know roughly where to look (I'm in Minnesota, big iron range up north, largely hematite, some magnetite), It's more of a matter trying to know if what I've found is hematite. Right now, my tactic is to pick up any rock that's red and doesn't crumble in my hands.

Ayy fellow NE Minnesotan. Like the other anon's said look for structure maps, bring a steak plate, and try checking the for the Mohs Hardness scale for hematite or the rocks that would carry it. Bear in mind, in the Northland our concentrations of Hematite and Magnetite are pretty low overall, we just have large quantities of it. You might have better luck looking for BIF's

Just know what it looks like and it's basic properties, and more importantly get a geologic map and find outcrops on it. Seriously though it's pretty fucking recognizable lol. Also that pic looks like a chunk I found up in the red mountain formation around birmingham alabama, solid metal as fuck my hammer bounced off and sparked, and it was altered from limestone and made up of a bunch of tiny organism, pretty cool. It was literally everywhere, just laying in piles along the road as it eroded out of the road cut/cliff faces.

Has anyone here tried to actually do this? I tried to make a thread on /diy/ but no one has the expertise it seems. I made one attempt and it was a failure

Op here-in what way did you fail? I've watched dozens of videos, and the thing I'm most concerned about is picking out the right rocks so I don't end up with a bunch of slag. That and wether I should make my own charcoal or just buy a couple bags (if that was your thread in diy)

Sorry to hijack this thread but could anybody identify this? I can't figure out if this is petrified wood or just layered granite. I'm leaning toward plain old granite/quartz

I'm the geologist from just above, it's fucking easy you go get the fucking metallic rocks. To avoid the slag avoid silicates shit like chert look for the shit that is like metal. You know what metal is like, right? Shiny, hard, not vitreous (glassy).

Seriously elementary school children can identify hematite.

Picture is shit but probably granite type rock.

If it were petrified wood it would be like chert, not granite lol.

I didn't use hematite rocks, I used pure magnetite powder Fe3O4. What I was talking about was the actual process of smelting. I used cement chimney block as the flue and it melted into the bloom and I had almost no slag which is necessary to have a reducing environment

I used kimmel anthracite nut coal from tractor supply as fuel instead of charcoal and I'm not sure that was a good move, but I needed to keep it budget friendly seeing that 200 lbs of coal was 30 bucks and charcoal is 5 times the price for the same weight. i hope the geologist anon can tell me if that might be an issue, since my understanding is that coal and charcoal are essentially the same but coal has marginal amounts of sulfur in it.

Petrified isn't going to be made up of an assortment of different crystalline mineral grains though.

Pick up some nitric acid, then dissolve a chip sample in it. If the solution turns a dark red, you likely have some form of iron ore. Neutralize with either ammonia or baking soda, then check to see if you have something that looks to be iron hydroxide (should be something like rust colored).
