Hello everyone, my name is Angel, this is my very first post and i hope i am doing it right.
I need your help, i am a cell phone and computer tech and i get lots of cell phones and computer parts into my hands every single day i have to sort cables and gold plated connections, some of them look very solid and thik for for gold content, i used to throw everything to the recycling garbage but always bothered me knowing that small amount of gold will ad up in time so i decided to scrap it and save the gols pins and cables.
Over two years it accumulated a lot so i decided read about gold recovering, i noticed most people got it wrong on the presipitation so i decided to try with small amount and this are the steps i followed:
Clean, and depopulate connectios, most of them are small gold fingers, i added pure water then add small amounts of nitric acid and let it react, then i decanted the acid and added more water and acid and left it for few hours, it looked like lots of gold flakes floating arround, probably half of a gram then i decanted the acid again and without adding more nitric acid i added more water just enough to cover it, i then added hydrochloric acid in small portions untill i see no reaction, i let it over night, next day i checked all the gold have disolved so i proceed to precipitate with SMB, nothing heppened i left it for two days but nothing will happen, i asked a jewler and he told me to add copper until it stops reacting, i did add copper but nothing precipitates, i only see white cloudy stuff floating arrown, i followed direcctions very carefully something along the way i did wrong
Please help
