Rainy Day Roasting Rocks

[southfork]

Raining today a good day to roast rocks ten minutes in the furnace and their ready to crush. It makes it easy to breakup into smaller pieces to feed the jaw crusher then a trip through the chain mill. I have found with our ores two trips through the chain mill increases our recovery of gold. Just pieces of float uncovered while raking and burning I just toss next to a tree to pick up latter. Some of large chunks gets tossed into the burn pile for a pre roast then single jacked into pieces that will fit into the small furnace. The black rock is a before the roast and reddish after, then dolly pot and a small line of micro gold to the left of the reflection. I have a bucket full to crush maybe I'll have some good luck Happy Mining

Are you getting gold from this?

Southfork I'm glad this process of yours's works for you on tossing rocks to a certain spot and pick them up on the way back , BUT it didn't work for me because (back when I could meander around prospecting, I never ended up going back in the same direction ! there was ALWAYS a "OH, look at that monument" and I went in another direction ! It never failed to happen to me ! BUT then again if it works , keep it up !

It's on our property so sooner or later I'll find it again hopefully.

Yes, that's the piece I crushed in the dolly pot second picture of micro gold. Most of the rock with the red oxidized / weathered look contain gold some more than others. The grainy black veins are sometimes loaded with free gold also this stuff won't set the detectors off. Unless there's a good pinch in the pockets.

Interesting ore there. 👍

I finished roasting

Interesting ore there. 👍

I finished roasting the bucket one piece maybe Diorite caught my eye. The bottom piece in the furnace I gave it a whack looked blackish inside and hard as hell. I crushed and panned a small piece and found a speck or two. Now I have a bucket full of mostly quartz rocks to crush maybe tomorrow if the sun is out. The gold is near the top middle a speck with some micro dust.

Naive question about roasting rocks.

I picked up this ugly rock in NC, along a hillside in a gold mining area.
It's quartz, I think.
It's the heaviest rock I've ever found.
I don't think it is just quartz.

What would be the best way to roast it, dissolve it or investigate it.
Any advice would be helpful.
You guys seem like experts in this.

I'm no expert by any means but wouldn't a scan with a metal detector let you know if there's some sizable precious metal in it (not specks of gold )

Yes, if the gold is concentrated

yes, I've found rocks that just seem too heavy for their size. The detector never sounded, but after crushing, some of the best gold from a single rock was panned. From what I can tell, something that looks like a useless rock, can sometimes contain internal gold, even though the outside provides no indication. I'm probably wrong, but when I find something that seems too heavy, I crack it, and use a high powered loupe. Hope you find good gold in your roaming.

Many pieces of ore will leave a smile in you pan without being detectable by the best detector tor. They also many times won’t have visible gold that a person could even see with a magnifying glass.

Yes, I know. I'm managed to get my sluice tuned so I get that micron gold. I didn't see gold in my pan until I'd accumulated quite a bit, but once you have enough, it does show. I aways recycle my cleanup sluice material, and always find this type of gold that was initially bullied out of the cleanup sluice first run.

Thank you sir.

It didn't sound off on the metal detector in the 11kHz range. I guess I should have tested it at 54kHz.
But it just seems too heavy to be plain quartz. And it was calling to me...lol
I'll yest in when I return home next week

It’s basic grade school math to check the weight if you have the proper scale.

Unfortunately, I don't have a scale.
I only get home two days a week, Saturday and Sunday.
So, trying to do anything is difficult.
Always something else happening

Understood. Get a foot long piece of 12” well casing and weld a plate on the bottom. Use a piece of industrial scrap axle to use as a weighted hammer. Then screen and repeat then pan out. Small investment if you routinely pick up rocks that you wonder about. You can pan into a WallMart rubbermaid container.

Yep I've made a lot of these and some smaller ones for finer crushing , plus I've made several chain mills with Gas or electric 1/2 H.P. motors.

Cleaning the concentrates from my latest bucket of rocks. I'm guessing about forty pounds of material across the ribbed sluice. Extremely hard to pan the black sands are so fine and heavy even the mercury is having a hard time passing through. I just keep working it in the pan super fine gold particles are all through the concentrates takes forever to get a line to pick up. You can see the gold on the top of the mercury ball looks like gold paint.
