Hi Ragnarok84,
You have arrived at the finest repository of information for the hobby refiner, in the world. Welcome!
Here you will find the answer to any refining question you can imagine.
Only one problem....., you first have to look for the answer yourself. It took me a while to figure out why everyone is so adamant about this, as I am an impatient guy, who likes fast answers. Fortunately, some really nice people explained the forum culture to me, and as a result, my refining knowledge grows daily.
Go to your "user control panel" and under "important announcements" check out "Tips for navigating and posting on the forum", and "Board policy". I cannot stress how important this is to your stay here, mate.
The "powers that be" are inundated with answering similar questions more than once, and sometimes get a little sticky with what may be perceived as a need by new entrants for instant gratification with minimal input (like I used to be), so in exchange for their vast, and I mean vast, knowledge, they ask only that your prove your sincerity by doing the required legwork in the form of the suggested reading, specifically the free download of C M Hoke's seminal book, "Refining precious metal waste", (The forum's " bible"), prior to posting.
Once again, this link,
http://goldrefiningforum.com/phpBB3/viewtopic.php?f=60&t=21374 will really make things easy for you. Send me a pm for "New to the forum" questions, If I can help, I will.
