extracting.... Answered

can anyone tell me how to extract platinum from catalyc converters? (pardon my spelling)


In California where unfortunatly I live to have some of the acids in your possesion is a crime (In posession of a industrail controled chemical) besides this, which at least is easy to get around( dont get caught)..anyway its all just way too much of a pain in the butt. You need large amounts to process, you indeed must be careful, inhaling fumes and posssible splashes on skin means you need chemical grade aprons and gloves ect... Then after the extraction you must nutralize the solution. If i had very old millitary bread boards with lots of actual gold wire inside i suppose then it would be worthwhile. Lots of things have only one millionth of an inch plated..like most new costume jewelery or a cheap plated ring. Older plated items from jewerly contacts had much more gold and if you go back far enough you will find gold contacts not plated. But like i said lots of hassel, lots of time not enough return plus you must put up with the arragant attitude of anyone with a high level of chemistry background thinking that you are a complete moron and couldnt learn in one year what only takes commoin sense and a little time to learn.

The best I can come with on a moment's notice is "no".

The platinum (and palladium and rhodium) in catalysts is very unreactive, so needs powerful chemicals to make it do anything.

You'll be talking very high levels of corrosiveness, toxicity, possibly very high temperature's and pressures and noxious fumes.

Since the cash value of the metals in a catalytic converter is about 30GBP, and a second-hand catalytic converter sells for between 30GBP and 100GBP depending on model, you'd be better off simply selling your catalytic converter, rather than poisoning yourself, blowing yourself up or dissolving your workshop.

u were the the one who told me where to get liquid nitrogen in my forum.

The only acids capable of reacting with many of the metals asked about are nitric, sulfuric, and phosphuric acid. These chemicals aren't readily available to people, or are not wel known as the named acid. This is intentional. nitric and sulfuric acid are very powerful components for manufacturing explosives. phosphoric acid is used extensively in the production of illicit drugs. Anywho...Just off the top of my head, you could just try oxidizing all the other components of the catalytic converter. platinum, Paladium, and rubidium don't rust very easily. The one draw back is that this would take a bit of time.

and if this does'nt turn up any answers I can always scrap those windows 95s in my basement for gold, does grinding up the chips and melting them down work?

You know there's very little gold in computer chips, right? They are mostly silicon, aluminium and plastic. If you want a money-making scheme I suggest you mow people's lawns or something, it's more profitable for a single person than trying industrial precious metal recovery.

Or at the very least stop looking at the $2000 an Oz metals.. Copper which is worth $2 to $4 a pound scrap can be recycled and it is easy to find at dumps and recycling centers... I just picked up about 200 Lbs of wire at the dump it was even rolled up and mostly long lengths of 8 and 6 gauge wire, I'm reusing it, but some thing like that is $500 worth of scrap, and people just toss it out... all you have to do is ask the recyclers how they would like it, most like it clean and bright which with a wire ripper and an hour it would be... ((( Don't go cutting phone / power cables the recyclers have real issues taking huge amounts of cables from people they don't know, the kind that just show up with a few thousand feet of phone cable with the dirt still on it and property of AT&T; printed on it, but if it's stove plugs they know you didn't just rob a sears appliance center for stove cables ))) And if your after the platinum to make some thing like ring, talk to the recyclers they may trade copper etc for other metals if you ask the one by me is very helpful in finding odd metals, or take the cash and buy some.... Power cords on old stoves and dryers are also another great source copper wire, stove and heating elements contain nickel and chromium.. Some times you can even find old lengths of copper pipe, burnt out electric motors, coils on fridges are normally copper, microwave transformers are wound with copper....

ya but there's also a thrift store that sells old and broken pcs not to far from home. I've been told that older pcs tend to have more than newer ones, and aluminum is still sellable. I've been trying new methods.. oh and kiteman do you know where to find these chemicals/corrosives?

. Due the the Pb and the high heat (and the very small amount of Au and Ag involved), recovering precious metals from PCBs is not practical for a DIYer. You will poison yourself and the neighbors. As with Hg, this is best left to the ppl with the proper equipment. . Most PCBs are fiberglass, so very few chemicals will get rid of it. Most of the traces (where the Au is) are buried in the board.
