[anachronism]

$10000​	1000 kg​
$1000​	100 kg​
$100​	10 kg​
$10​	1 kg​

So dear sir, you're saying that this might be the case?? This might be the possible yields??

At $10 per Kg they are paying you on the copper content too. You won't recover that so my advice would be to sell them whole.
That's what I get for them in the UK - so please bear in mind regional differences in markets.
