i took 5,8kilos of(plastic) pentium 1 and withdrew 1,8 kilos of cover lids---with the 4kilos i added ar---the ar reacted and cleaned the pentium of its gold--when filtrating the ar ,i was left with 120grams of a magnetic powder with visible gold in it---- i took this 120grams and boiled with nitric1:1 and distiled water---when brown fumes ended(about 1hour) i withdrew the becker from the heat and added more distilled water---here happened something (for the first time i ever saw),the reaction revived and almost boiled over the becker.i filtrated the liquid and was left with 49grams of powder---to the nitric liquid i added naclo3 and plenty of red palladium powder formed--to the 49grams left i added ar again and precipitated the gold with smb----to the initial ar (the 4kilos) i added urea and then smb and leaved to rest till today--the various funny thing that happened:1 the precipitating the 120 grams of magnetic powder-2 the reviving of the nitric reaction just by adding water3-the original ar did not fizzles when i added urea--- probably i will get little gold from the original aqua regia solution because the larger quantity was in the 120grams(49grams) and probably i will have more pd in the original ar solution---today i will have the numbers (results) for gold and palladium in 5,8kilos (with lids) or 4 kilos (without lids)
