I was doing some more reading and found this tutorial on retreiving gold from pins. I was wondering if anyone could tell me if i could just use a nitrate salt inplace of the conc nitric listed here http://www.goldnscrap.com/index.php?option=com_content&view=article&id=86:high-karat-gold-21k-23k-refining-and-melting&catid=25:gold&Itemid=20 . This i think would be my prefered method for processing IDE pins and pins from telephone connections. Nitric is kind of dificult and expensive to obtain where im at So if i can use a nitrate salt here that would be great.
