ok i think i said to much in "simple filtration question no one addresses"
HI buy the way
1)dilute 200ml 65%(HN03) with 200ml H20
2)add 1 kg of assorted pc connector pins (pci,isa.rs232,rj45,video,jumpers,ide,scsi all (male and female)
3)let sit till reaction end's
this is where i'm confused
the gold foil is visable at this point it is mixed with a blue sludge at the bottom
i can wash it, heat it, add hot (HN03) decant it, but the blue sludge is always present
let me clarify (and i am refering to 2 previose batches) and 1 I am going to try again fresh
if i try to filter: the sludge clogs my filter instantly ,But wait is'nt the sludge undissolved
base metal and if so why am i filtering when it will just mix with the gold in the filter
so far all the procedures at this point , holks book even the wrong procedures all
say the same thing FILTER OUT ANY AND ALL SOLIDS Did i miss something here?
I understand that the (HN03) is to dissolve base metals to make it possable to eliminate
them from the equation
i under stand washing and rewashing to help rid also the (HN03) and impurity's
and i can even get the water in my beaker clear
but i cant put it in my a/r solution until the sludge is gone is this right?
dam i did it again. i guess you guys r lucky i talk way more than i type
thx again for all your help
ps: made Stannous Chloride and its not clear my next post
