hello all i know you dont know me but i have read many of your post and been here probably just as much as youtube over the last 2 years. (which is ALOT) i am very thankful this place was created and has help me more then i have room to pester you with. <3 with that being said on to the "misplaced" Gold lmao....
allright so here the deal been learning reverse electroplating straying away from nitric but i did a good 3 lb batch of gold plated pins. now after taking the sulfuric into water and neutralizing with (ALOT) of baking soda then rinsing, decanting, hcl-ing, filtering, bleach and hcl, we get to the SMB. now i think my issue is i have dropped far too much in. (super excited i was) so seems my gold will not precipitate. i haven't emptied the chloroauric but seems quite light green with very little precipitation.... quite odd seeing as i did about 200 grams of processor pins besides the other 3+ lbs of ide drive, motherboard and such gold plated pins. so out there sits my chloroauric with an odd tint of light green. i have yet to leave it over night but have an uneasy feeling something is wrong.... (done this a few times with other processes and worked beautifully)
so my questions are:
1. if i did use too much smb how do i get it to drop gold at this point?
2. is there anyway residual baking soda would screw up the process
by nuetralizing any of the other chemicals?
3. does it matter how much water you actually use?
4. and how the heck am i ever supposed to figure a guesstimate on how much gold so as to add the proper smb amount? (lmao that one tickles me)
lucky me i did short vids on it and can grab pics from that if need be. heads up though i made a boo boo as well and got rust in my rinse bucket which wasn't an issue because i still had to hcl it again anyhow
thank you all for your time, patience, and in advance for your responses. i look forward to finally being able to chit chat with some of you on this wonderful work we all share! <3
