This forum is friggin awesome! I've been reading through so many threads here that I had to start jotting written notes! I love it! I just have a few questions. I didn't feel they were quite "Help Needed" material, so I'll post them here:
#1. SMB. How selective is it in precipitating? I may have a scant amount of Cu in my AuCl3. I base this on color of the solution. only under florescent light does it has an ever-so-slight greenishness to it. If there IS Cu in my auric chloride, will the SMB drop it too?
#2. H2O2. If I use the higher percentage solution from my local Beauty Supply World, can I merely adjust the amount used in solution based on the apparent math? (i.e. 300ml 3% = 30ml 30%?)
#3. I'm kicking myself for asking this because I KNOW I read a thread detailing it here, but I can't find it again. How to clean the base metals from spent AP solution and make it fit to be re-used?
#4. Fe. After scouring my workshop for containers, I found quite a few containers of perfect size for my reactions. They were used to store sets of old tire chains for the past 10 years and the white plastic pails are now rather rust-stained. Will this effect my results?
So my first batch, which is currently 200ml AuCl3, awaiting SMB via UPS, I'm predicting at least 1 troy scruple fine Au, based on the amount of foils from 1lb trimmed milspec pinboard. Photos I'll post in the Gallery!
