    Since our claims here in Colorado are only a few miles down stream from the head of the San Miguel River which is in Telluride we have a great deal of Tellurides in our Black Sands. I have been told these can contain as much as 20%-70% gold once processed. I have been experimenting with some techniques of removing the iron sulfide from the black sands with some luck, but not to the amount I would expect.

     

     

    I recently tried a technique using salt and then baking at 1000F for several hours and too my surprise there is a great deal of gold but it is so fine it's like dust which makes it impossible to separate from the rest of the black sands. These super fine gold pieces would probably easy to pick up with mercury but of course that is dangerous and a violation of the law. I have also tried to use a product called Amalgamite but your gold gets trapped in the Amalgam and no matter how longer I cook it for in a kiln the process does not work as advertised. Plus I think they use Zinc in the metal and even outdoors I got deathly ill after spending a day trying to burn it off.

     

    Something also I noticed that was strange is that the black sands that were magnetic contained a much higher concentration of gold. Does anybody have a proven method of cleaning these up and then smelting them without having to use harsh chemicals, mercury, or spend 12hrs baking them at 1000F?

         Benjamin, there is an old saying that states " a countries industrial might can be measured by the amount of acids it consumes ".  So with that being said it is hard not to use some chemicals in refining.  A book that would help you is " Recovery and Refining of Precious Metals " by C.W. Ammen and chapter 11 covers the refining of black sands.

         One thing that I suggest is to keep a detailed log book of everything you do for future reference.  Right now I am working on a complex ore that contains 39 elements in it, plus Au, Ag, and PGMs.  The first thing I do before using chemicals on an ore is have a x-ray spectrometer analysis done on it.  This tells me whats in it, how much is in it and most importantly if there are any TOXIC METALS to deal with!

     

         NOTE!! Because many people will see this post DO NOT play with chemicals if you have not been TRAINED in handling them and FULLY UNDERSTAND what can GO WRONG and know all the SAFETY PRECAUTIONS needed!!!          Ron

    I am a long lasting trained professional in Nuclear Materials but my Chemistry is not so good. I will look into the book you recommend, besides myself, recently got sick, I had a friend pass away that was smelting lead weights into forms and he passed away from cancer.

    He was smelting whatever outdoors on a regular basis, I did nothing even close and was using "Non-Toxic" materials and woke up puking for three days.

    There has to be a way for us to come up with a genuine process and then patent it or copywriter it?

    Forgive me if anybody takes this the wrong way, I am just looking for a safe way for small time miners to process gold without causing toxicity to themselves, their neighbors, or the planet?

    Pleas give up your recommendations, and make sure they are legal?

    Ron,

     

    I have hear that quote but I thought it was made during WWII by either the Russians or Germans? After all it takes acid to build explosives and refines metals.

         Benjamin, calaverite contains Au Ag Te2 along with other elements that can be running with the ore. The Te being tellurium and Te is in most cases mildly toxic.  The fumes of Te can cause dry mouth, drowsiness, metal taste, headache, nausea, and garlic odor of the breath.  Ingestion can cause abdominal pain, constipation, and vomiting.

         I have yet to find a one stop source for info when looking for answers on refining that come to mind and that is why I have several books on the subject.  Another good tool is this site for toxic info of elements.     www.lenntech.com/periodic/elements/te.htm

         Hope this helps to point you in the right and safe direction.     Ron

    Being a Nuclear Medicine Tech I am required to keep the most extensive logs and checks on equipment, more so then anybody else in the Medical Field that I know of, with maybe the exception of Radiation Therapists. Because I have a type "AAA" personality I keep extensive logs on everything I do, but I am losing faith in the internet because so much of the information is either made up or written by idiots that don't have a clue what they are doing. There was a time when the Internet was as usable as a library but unfortunately it has become the realm of the mental midget looking for their 5 minutes of fame.

    "abdominal pain, constipation, and vomiting." and that was just from the fumes.

    Thank you for the recommendation on the book.
