I've been told there's gold in these rocks

These have been HCl'd with minute peroxide for quicker reaction for about 24 hrs.... and know what is happening chemically speaking... then a baking soda bath for an afternoon.... And a nice soapy water shakedown and rinse... Just still unsure of my judgement

Crush em up and pan em.Or get a Falcon MD-20.Good luck.
Place the rocks on a cement floor.Cover them with a rag (to protect your eyes). Crush them down to this size with a 6 to 10 pound sledgehammer(only takes a few minutes). Then pan the material .

If, after following RTRs advice, you get nothing, please realize that much of the gold bearing ore processed by mines today has no visible gold. That is why professional miners utilize assays.

Time for coffee.

I've actually done that taken the concentrates to local jeweler and he said there's nothing but I've done AP method to get rid of base metals. Then AP again to get gold chloride and then dropped gold with smb. And got enough 99 dust to visibility see it on bottom of jar. Tried to smelt but haven't gotten it quite right. None the less if it ain't a "dirty gold" placer nugget then everyone I talk to says some lame ass **** like that might be melted pyrite or that's mica...umm pyrite don't melt it releases sulfur and leaves iron oxide behind...mica crushes to a powder and swirls into the water as u pan... I know what I'm looking at but can't get repurposed back into button...I've got tonnage and I'll be damned if I live in siskiyou county and don't got gold bearing rocks...

Also what does graphite do/look like when crushed and heated

If you want smelt gold, you have to add powdered lead. I have made my my own lead flux. I melted a whole bunch of lead in a crucible. Let it cool. It fell right out of the crucible and looked like a big bullet. Then I took a shurform tool and and filed some off. Mix it with the ore, add some borax and powdered glass. Add some bicarbonate of soda too. I made powdered glass from some beer bottles. In the end you have a lead button. Beat the slag off the lead button. Put the button in a cuppelling dish. Heat slowly.
The dish will absorb the lead, what is left is a gold silver BB. If no silver is present you will just have a little gold BB.

Get a sample and send it for assay. Take the guesswork out of it. The assayer can also give you an idea of what you have in the ore of it is refractory at all.

 

[Clay Diggins]

Get a fire assay. It's the only way, it's cheap reliable and as accurate as your sampling ability.

Chemical reduction or XRF can not produce a reliable assay.
