Congrats on finding platinum! What you are seeing is the platinum acting as a catalyst- causing the second oxygen atom to be stripped off the H2O2 (hydrogen peroxide) leaving you with water and oxygen gas (bubbles). Nothing helpful is happening to extract your platinum in this process.

What would i have to do thento get it ready to sell anything? thanks

The only place where PT has been found in the US is in southern Oregon, where a mine existed along the lower Rogue River. At that mine, most of the product was actually gold. The PT was an afterthought.

Pt is also found along the beaches and land around Crescent city nor cal, and along the golds bluff beaches/ miners ridges to the south and north where the tertiary Klamath once flowed.... bring it my office for a XRF exam and we can see whats in it and whats in the matrix surrounding it.......

I think It's been found and mined in small quantities in other states, GA being one.(I'm trying to find the link again, just in case I misread or wrong)

Not picking on you, I was just proud that I actually half retained something since it usually doesn't stick, since I've been trying to study GA Geology recently.

I see what you meant after further looking into it.

Looks like there's also some placer Pt in the UP of MI from the glacier. I've hit 2 pieces of fly poop so far on the beach. The beach material has a lot of the goodies found around the Wawa Ont. region. There is a platinum mine up there.

There are some beaches up in AK that also have Pt in the black sands.

california has lots of platinum.

crush it and pan it.

if it's too small to pan out. crush to powder and roast it to over 3500*F to melt platinum. 6000*F to melt the osmium, iridium, and a couple other metals.

Washington State has platinum and one of my claims on the North Fork of the Salmon river in Northern California has up to 1oz. nuggets of platinum in the river. Don't forget Alaska, lots of platinum there too.

There's also the Stillwater Mine up in MT. A commercial platinum/palladium hard rock mine. (20 years ago I worked for the company that owned it.)

I am going to throw some cold water on this party.

What does the assay show? Please note that there are many minerals that react to hydrogen peroxide, so if that reaction is your only evidence of platinum, before going in head first, please have a proper assay done by a qualified professional. That will tell you if there is actually platinum in your rock.

Time for coffee.

The internet is a great place to get mis-information yet I still keep using it successfully to figure out how to fix stuff.

Here is a snippet from the 1886 California Journal of Mines.





I find it especially interesting that the Trinity River gold dust was marked down $2 to $3 an ounce!I had always heard that the early miners threw out the platinum - maybe this is why.

It is true that platinum is found in the North Fork of the Salmon, not in abundance, but I have a friend that has found pea size nuggets while dredging.

I stand corrected. Thanks all.

Platinum is fairly common here in Del Norte County, Ca. I have recovered quite a bit while panning various areas of the Smith River.

Silver will also react with HP, if you put HP at 100% strength on silver it will instantly turn to steam. HP - " Hydrogen Peroxide " The old Jet Packs made in the 1960,s used this method to create thrust, Bell and Howell made these back then, back in 1962 I got to see one in action at the Seattle Worlds Fair, so awesome, I was only 7 years old. To bad they could only carry enough fuel to last 3 minutes.
