Just posted this comment to Dirtychemist youtube video - For some reason when I posted it to his video (comments) it came out as one long post instead of broken up as posted here ----------------
Dirtychemist - This is Kurt from GRF (the - "Gold Refining Forum) you posted this video there on GRF --- I posted a reply in that thread pointing out the MANY mistakes, mis-information &/or incomplete information in this video of yours -You did not like my reply so you posted a "very rude & combative" reply which has now resulted in your being ban from that forum which is sad because you have no idea just how much you have thrown away concerning the VAST amount of knowledge & information at your finger tips concerning the recovery & refining of precious metals
There are members of the GRF that do/have ether owned &/or work(ed) for VERY large world class refineries & many of us that have been at this for many years & have reached a level of doing this as a small (home refining) "profitable" business --- SAFETY is your number one concern - & when we see something like this where safety is thrown out the window you can expect that we will comment in the hope that the poster will heed our warnings & start doing some real research to learn better & safer ways of doing this
Apparently (based on your "rude & combative" replies on GRF) you find yourself above those of us that have much more knowledge about metallurgical chemistry then yourself
This video is horribly filled with dangerous "mis-information" (as I told you on the GRF forum)
Using ammonium nitrate for making "Poor Mans" AR --- IS NOT a good choice of nitrate salts (used in place of nitric) there are MUCH safer nitrate salt's "available" that work just as well
Adding alcohol (of "any kind") which you used to prepare your DMG - to solutions of dissolved metal solutions is VERY dangerous - it "can & will" - PRECIPITATE - explosive compounds (of certain metals) so explosive they will explode under there own weight (as the precipitate builds up) & while wet (still in the solution it is precipitating from) --- alcohols have NO BUSINESS being used in refining
Chlorine is a "much" better oxidizer then nitrates for leaching PGMs from CATs --- I know this because I worked for one full year with a local scrap yard setting up "very" large volume leaching of CATs (35 gallon reaction vessels stacked "full" of CAT combs) --- its VERY dangerous & requires "special" set up & operation
Your thread (on GRF) has now been moved to the "Rogues Gallery" which is where we put "trash" which is what this video is - Anyone watching this video &/or reading this comment should NEVER follow this advice &/or any other advice posted by Dirtychemist --- he does not know what he is talking about - if you want to learn about recovering & refining PMs (precious metals) go to the GRF where you will learn from real pros - we are more then happy to help "those willing to learn
