getting silver off of copper is rather easy and on the forum there are a couple fellas who have different methods they have used for the process..... on starting recovering and refining in 1970 and retired a few years ago, and wants other folks to get into the hobby and make it a part or full time business and is willing to share the information to anyone who is willing to learn by reading what is written already and asking questions where they crop up.... [others learn from questions too] most of the advice will boil down to purchasing a book written in 1940 by C M Hoke called Refining Precious Metal Wastes which will set a person back about $70-90 depending on where they purchase it from.... of course a person then has to understand the safety of 1940 and the practices of today are somewhat different but the tools and formulas have not changed, merely the prices.
You will see the theme presented on the gold refining forum many times over as the book itself was written for people in the jewelry and dental trades who are not chemists. The lady who wrote the book had at the time been corresponding to such people for over 15 years and had the belief that many people would benefit from the book... that coupled with the fact that many refiners dont want people to know how simple certain recovery techniques are
which keeps the profit in the hands of the big refiners who do not really hve much for competition.... which is changing.
Biggest thing to tell people is not to fall for the ebay hype of high values on scrap gold, and to find and purchase scrap when you can see it and hold it and weigh it out.... and test it. Next thing is although the acids used can be harmful, as long as safety precautions are used and proper disposal methods are followed both the person and the environment will not be harmed..... once you get onto the forum read the various helpful pages on such issues.....
Other advice is to get a couple spiral notebooks and take notes and have the notebooks at the ready as you recover and refine like folks already do in the shop while working a project] and download the different books that are in the General chat under "Chemistry Books" particularly on page 3 called "GOLD REFINING FORUM HANBOOK VOL 1.pdf" posted by Aflacglobal, it is condensed from the forum pages and he is working on second volume, this one is about 125 pages of the forum that have recipes and pictures and the questions already asked and answered [including a couple questions of mine].....
anyhow, I am not trying to take away from HT, but merely to give people the information for free what others ar charging for on places like ebay [tm] and it fits into the shop work or laboratory as it were.
