Hey Palladium,
First thought --- thanks for all the links, they are very useful and would be even more so if my computer wasn't jammed up with music and game downloads. Don't get me wrong, I don't mind good tunes and even taking a moment or two to find Waldo as I await a dental torture session, but there are ------ limits.
Second thought --- thanks for the pic, when time allows I'll have to google her and see what I can dig up. Truth be told, for her day, she's not a bad looker and, politics notwithstanding, I'm willing to bet that, were she approached respectfully, she very well might have been willing to join one for a sherry or three. It's rather difficult to wrap myself around that thought, as I, for some reason or the other, conjurred up an Annie Oakleyish vision of Good Ol' Calm (not unlike Steinbecks accurate portrayal of Doc Rickets in his novel "Canary Row") and was thinking more in terms of tossing down a couple of pints with her rather than sherry ---- not to mention referring to her as something other than "Comrade." The present image and title will, however, allow me to concentrate more on the science than the scientist and I'll probably get a whole lot more done as a result ---- so, I thank you.
As previously noted, I am doing my best to get through Comrade Hoke's treatise before I proffer any questions. I have seen far too many before me fall victim to the consequences of not doing one's homework prior to tossing a few question marks out there and honestly can't blame anyone for taking umberage at having to explain what redox reactions are every day of the week, but I do have a couple of questions that you might be able to help me with that I don't believe are covered in C. M.'s work. When I last ordered supplies, I purchased anhydrous Stannous Chloride rather than powdered tin to make my Au indicator fluid and, as yet, have not seen anyone describe how to prepare a test kit using anything other than powdered tin. I tried disolving some in distilled water and found it to be water soluble, but when I used it on a solution rich in digested karat gold the paper turned black, which I hadn't expected. Is it possible that my karat gold solution is too concentrated, or have I purchased a quarter pound of material that I'll never be able to use?
Lastly, in order to prevent major losses due to dumb mistakes, I've been working at the micro level in test tubes and will continue to do so until I am well practiced and actually getting mathematically predicted recovery from prepared Au solutions and, as suggested on the forum, I have been using SMB as a precipitant rather than cementing values out on copper scrapers as has been my practice. The bottom line is that I don't believe that I am getting the recovery that I should be getting and, honestly, have yet to find the quintessential how to use SMB thread yet. While searching for such a thread, I found a comment from someone who was extremely excited about the results he achieved by using sulfammic acid (a quantity of which I purchased), but I have yet to "rediscover" that individuals primmer on exactly how to go about using it, nor do I remember his name. So, believe me, I'm more than willing to do the leg work, but I really could use a push in the right direction ---- if you can help me out I'd greatly appreciate it.
Thanks again for Comrade Hoke's pic.
Regards, Lance
