i am recylcing different motherboards from half an year and i am regularly facing loss as not properly understand the tricks of dealing with market! well i decided to stop more losses and make a more accurate velues of precious metals that can be recovered from pcbs. here is my story of last deal!
i buy 70 pieces of p4 motherboards,2.5 dollars ( 250 RS in pakistan)per piece... 10 p3 motherboards 3.7 dollars each, 12 p2 motherboards 4.9 dollars each. no ram, no processor! so first i think to remove BGA chips only, hthat weight only 250 gram, so i can get 2 gram of gold from these. as i ask the seller to rebuy my boards without BGA, he offer me 1 dollar per kg. by this
92 motherboards= 217 dollars.
gold from BGa=2gram= 80 dollar.
remaining boards= 46 dollar. i am loosing approximately 86 dollars without acids+labour+chamicals.
can someone give me an idea where i did wrong!
can i process remaining whole board via electrolysis. will this recover gold from plated items?
