Hi, i am a real newbi on this and i was hopeing for some help on this.

If i have a mass of mostly different metals, Iron, Silver, Gold, Copper and some other ones and there could be some solder in there as well. How would the best way of chemacly separate them look like?

They are just fragments, very small but mixxed together.

Any ideas?

Thank you

Hello knofan: I'd like to welcome you here to the Chemical Forums.  But I'd like to ask you to trouble yourself to read our Forum Rules{click}.  You agreed to these rules as a condition of signing up for our forum, and they apply to you, whether you agree with them or not, or even if you're unaware of them.  Briefly, we don't dump complete answers, we try to help you help yourself.

We're glad to help.  Lets get started.

Ok, that's clear, and easy to understand.  We can look up the individual properties, or better still you can, and try to work out a plan.

and some other ones

Other ... what?

and there could be some solder in there as well.

Which is made of, ... what?

I feel like I have to call you out on this, and I'm sorry to make an example of you, but what do you mean?  You've said everything, except "stuff, and junk, and whatever."  You've written a question, in a conversational style, but you wrote it, so you could have been more clear, if you wanted to be.  So why don't you want to be more clear and specific?  We can't answer your question as written.  Did you write it that way, just to say, that we don't know anything.  Because that happens here often.

What chemical methods do you know?

They are just fragments, very small but mixxed together.

How'd they get that way.  That could provide separation insights.

Any ideas?

Thank you

Lets try to work together to get you an answer you can use.

Hi Arkcon

Well, i see now that this is not the right forum for me. I will take my questions some where else.

Thank you anyway

Well it could be the right forum for you. Most of the people who come here are students looking for help with coursework - either homework problems or comprehension of difficult course material. We definitely want them to show some work because it's for their benefit - if we just handed out homework solutions it wouldn't help them learn the material. The rest of our visitors tend to be hobbyists or else just normal people who have encountered some issue in their daily life that may require chemical knowledge to find a solution. In this case it is still helpful for use to ask questions so we make sure we are addressing what is really your problem. Hobbyists and other people who are not trained in chemical sciences often ask one thing when they mean another.

It's not 100% clear which of these kind of people you are, but your question was a bit vague and I think Arkcon was just trying to get a better understanding of what exactly you were asking and why you were asking it. This helps us to help you. Ideally you may also learn something that you can apply to future problems without having to come here and ask for help.

It looks like one recycling attempt more of electronics scrap. So the solder is 63% Sn 37% Pb, being presently replaced by 3% Ag, a bit Cu, the rest Sn.

Depending on the previous operations, worthless epoxy+fiberglass may still be present, and sometimes tantalum which might - or not - be worth recycling.
