Usually much less.Yes doing the sums unless you can buy the Nitric and Scrap in bulk I can’t see how there’s much in it assuming a 4-6% yield. Which method would you use? It seems a few people have made it work using AR but maybe they’re buying large quantities of Nitric acid and/or scrap?
Depending on type of pins it may be as low as 0.5g per kilo or higher than 5g a kilo for the high grades, if my memory serves me right.
