ok guys i watch a video with this process. burning mlccs, crushing in ball mill. mixing lead + borax+ sodium nitrate+ sodium bicarbonate+ mlcc's powder!!!! melting in a crucible and flow in a mold. upper black sludge is broken and underneath get a metal piece. next they prepapre a round middle deep pot with sodium carbonate and a wood ash. put that metal piece in that pot and give high heat until it boil and a black raw metarial start floating. then upper sludge broken and get a smaller metal piece than first one. now treat that metal piece with nitric. later with aqua reigia. silve and plladium percipitated out from nitric and gold from ar. i have some wuestions
1 is it necessary to use nitrates ? if yes then can potassium nitrate be used?
2 can i use same process to recycle mobile bords?
3 if i use this process for whole mobile boards, there will be alot of copper! how to remove copper as it will take more nitric ! thanks in advance
