Riddle bucket.

You can get loader mounted screening buckets so I'd think you'd be able to hire one somewhere. No idea where though, try the company mentioned in that link.

 

If you have someone local it's probably cheaper to have the gravel uplifted by grab, screened and returned.

 

Depending upon how bad the soil contamination is, could you just use the gravel for bedding pipes on? It's so cheap to buy in fresh washed gravel for drives, etc, I can hardly see it's worth screening it.

Good point, the only reason to try the screen is to avoid skipping it away. Local skip merchant has a grab lorry @£50/hr which may work out plus I have a long term need to grade woodchip.

Your local muck away bloke will probably uplift it cheap. He can screen it and use the soil in the topsoil pile and mix the gravel in with the crush.

 

Skips are a horrendously expensive way to get rid of soil and stone. The price accounts for landfill tax. A muckaway firm will screen and re-sell the stuff they take. Hence clean concrete is a free uplift as it can be crushed and sent straight out.

Over in Japan (which is truly excavator world) I was surprised how much they go for riddle buckets, instead of screens. So much so that at least some of the excavators there have some allowance made design wise for this, though I can't remember what this is. Anyway, they have buckets of the slatted type mostly, and you can see them all week long shaking there way through the heap. From what I saw, they shook a pile of fines, tipped the rubble off on another pile while hooking out bits of steel. Then they loaded the fines onto trucks by gently using same bucket, getting it to bridge in the slats, or if really fine using just the leading edge. Very patient job. oh and it really knocks the pins out, all the riddle buckets were on worn pins. Better shake once they've got sloppy, hey.
