Can anyone tell me how to do the hydrochloric acid test on rocks and does it work to see if there might be valuable minerals in that rock
It is not recommended to add acids to rocks that have not been assayed.
There is a lot dangerous compound the may be dissolved in acids.

When that is said.

As far as I know there is no acid test for rocks.
Adding to that, none of the valuable metals will dissolve in HCl alone.

No. To see what's in a rock you crush it to fine powder and pan it.
Or you have it assayed.
If you have specimens that need cleaning, as said, adic is not recommended on unknown rocks.
Here is a video of a you tuber i like to watch.
He tries out different acids and the result of Nitric was not good.
Strong HCl did the best.
Now he does not mention the dangers of things like arsenic, cyanide or mercury in the rocks, but they are all from the same mine. Maybe he knows there is nothing to worry about.
Geology reports of the area where you found it could help.

But if there is no visible gold, i would start with crushing and panning.
 
Geologists typically use dilute HCl to test for carbonate rocks, not for valuable minerals. There are qualitative tests using a few grams of material in a test tube to look for specific reactions. These tests, in conjunction with a bead test, can be accomplished in the field. A handheld XRF has largely replaced these methods in most mid-sized and larger exploration efforts

I'm not just looking for gold I'm looking for other valuable minerals and minerals that could be present in rocks

I'll thank you for your response is there a simple acid test for silver and rocks

I have heard that Carbonite rocks can contain rare earth metals is that true

As far as I know, there are no single simple "acid" test to test a rock for values.
You need to target certain elements with tests suitable for that element.
And for a test to be effective you will need to crush the rock finely.
Of course, if you are a seasoned "rock hound" many minerals can be identified by visual inspection.

Which rare earth metals?
It may be true since they are not rare nor hard to find.
They are just very hard to separate and process,
at least in a a way that do not drown the environment in toxic waste.
