Cell phones are the worst things I have ever worked with. I hate that stuff...is very labour intensive stuff (separation of batteries, disassembly, separation of plastics-rubber-glass, separation of gold plated parts magnetic/nonmagnetic, separation of board and components, treating the board to remove solder or trimming the edges to remove gold bearing pcb parts... no thank you). After processing all the gold bearing stuff i have come out losing money on it (i have to note that i was aware that i will lose money on it but accounted for learning money...the loss was not astronomical).
The problem i have found is the labour cost in hours, if you do not mechanize everything (shredder, grinder, separation before treatment, acids, refining, melting).
If you have an unlimited supply of mobile phones you may get in the business to refine gold from boards, but my advise is to find and mechanise all separation processes for you to turn on profit, or just disassembly the things and resell the disassembled the separated and sorted parts, you may end up making more money then refining.
By the way, i have processed mixed batch phones (from old nokia and siemens to more modern smartphones) I still hate that stuff
