shinny metal,heavy,and hard

[Edong]

hello everybody, i just wondering, if someone her can help me to id these metal it was found bottom of the ocean (40 ft. deep) a metal box size 4'x4'x6', and filled with concrete cement we demolish the concrete nothing inside ,and the only left is this metal which i cut it from the metal box thanks Ed

Umm no, the percent would be the WHOLE number part of it, ie the part on the left side of the decimal point.

that's less than one percent of both metals. in other words traces. not worth trying to harvest out. If you really really feel you have to go after it, Id use AR. but the cost .vs. what you'd get its not worth it.

what was the remainder of the base metal? did the report say?

aaron

OK my bad. Gold and Platinum are just trace minerals. That would be almost 1/10 of 1% of the total material of sample #2 is Platinum...right? Even less Gold. What is the base metal?

hi! aaron, thanks i don't have the report of the base metal ,according to the lab ,if iwant to find out, thats another testing which there's around 23 test to perform that would cost me , around 2 grand that's why i post it here i am hoping someone can help me ,i am willing to share atleast a pound, or two to find out what do we have ed

2 grand! So you asked the lab to specifically test for Gold and Platinum and nothing else? Is that how it usually works? Just curious.

Hi--Your discussion of the shinney metal is quite interesting. I wonder if anyone has thought to see if a magnet will stick to it? If it is ferrous, it should be magnetic at least to some degree.

yes it is magnetic ,but i was wondering why it never been destroy by rust,and the molding it's not done by factory,or melting plant,and there's waving of different thickness, and my last question is it common for the metal that is mix with some noble metal? hope to hear from you guys Ed

Probably quite a bit of steel made from recycled scrap contains trace amounts of platinum due to catalytic converters used on automobiles.

Japanese stainless steel? (magnetic stainless)

 

[Carolina Gold]

If you are on the right track with platinum, also try rhodium. it is a co compound in the catalytic process. It may be a casing to a large catalyst chamber and should also contain iron, carbon steel, rhodium. The rust on the outside that was removed may have been a result of sitting in a chamber with mild steel that rusted and became soluted in the trapped surrounding salt water and re deposited on the outer layer of the compound in question. a mass spectrometer would better narrow the questions. a burn on the compound will give off a glow of a specific spectrum which can be directly related to its elemental compliment.

 

[Carolina Gold]

oh yeah, i forgot, rhodium and platinum are highly resistant to corrosion. rhodium is more valueable than platinum per weight. Spot today was somewhere around $6000/oz for rhodium.

Is there a simple test for rhodium?

 

[Carolina Gold]

yes, it dissolves slightly in Aqua Regia but you need to stay the h^$% away from that acid. Evil stuff. Rhodium is the most expensive precious metal and is in the platinum group. Sulfuric acid will dissolve it (full strength NaSo4) and you can recompose it from that. mostly used for plating and making specialty wire. was worth only $200 in 2002 and was used more widely. so this guy may have found some really good stuff.
MORE INFO PLEASE!!! The stuff was definitely cast, probably against sand or concrete casing, and was broken from its cast, that is where you can see the lava like flow marks, cooling crystalization effect. there should be higher concentrations of certain metals in various areas as it congealed in its liquid form during cast. Like the last few cheerios in the bowl.

Sulfuric Acid is H2SO4

Answers man! We need answers!

ok the metal comes from the metal box, the thin one is the material that made the metal box the thicker one i cut it from one of the hook , the whole appearance of the metal box looks rusty,but when i cut those pieces, and soak it with vinegar i find out that rust on it was artificial,or intended to make it look like natural rusty metal, and the box has a bracket of angular metal bar around in the middle section, but all of it has been destroy by rust, and when i found it (the box)it was wraped with coral seem like it's been in the ocean for many many years sorry i can't expose the location right now for security reason perhaps someday, i guess that well answer all your question , Ed

As noted above,the thicker pieces were cut from the hook.The "lava like "flow marks are caused by the oxyacetylene torch used to cut them.

They are steel with less than 0.25% carbon,possibly a chrome moly alloy,which,when hardened resists rust very well.

I have been using an oxyacetylene torch for 45+ years so I can recognize a piece of steel that has been torch cut.No other metals can be cut with a torch.

scrap it, get some cash

titanium or titanium alloy

Hi Edong,

Have seen your assay report and it says, it is few mg per kg weight of your metal. In my opinion, those AU and PT are only traces in the base metal, considering the amount and percentage of weight per kilogram. Mg/Kg means, amount of trace metal per kilogram of the base metal.
I suspect that your piece of metal is a K-monel, a metal that belongs to stainless stell family. I think AAron is correct about his deduction.

[cwdigger]

well i couldnt tell you what it is but if it costs 2 grand to get it tested why not if it turns out to actually be rhodium or platnium it looks like you have several ounces there. If you dont get it tested youll be wondering forever, send me some Ill test it, another way to tell is melt it down like silver coins you melt silver and the silver stays on the bottom and the other materail comes to the top kinda like gas and water. Melt a small peice of it maybe in a kelt or furnace, then record the melting temp that will rule out a few things, 2ndly if it all stays the same meaning no other materials seperate its a solid material when it cools see what color the materail is then. If you dont want to try this then maybe you can test it like a jeweler would to test gold, buy you some gold testing acid and test it that way. please keep us posted on what this turns out to be and good luck.
