I brought home some quartz samples using your methods for identifying them (flat surface, brown layer etc.) . Then I fire assayed them ( Butler torch method) and they were coming out at 7 ounces per ton. Thanks. By the way Mr Butler taught the torch assay method for many years and lived in Bodfish Ca with his wife near your favorite hunting grounds.
@@soggybottomgoldprospecting3586 In the early 1900s two chemists, Shepherd and Dietrick published weight formulas for spherical beads of Gold Silver and PGMs and published research using Oxy Acetylene, or Air kerosene Torches. It's a Field assay method, so not as accurate, but very efficient and quick compared to a standard fire assay in a laboratory. In the 1970s Charles Butler refined the process, and taught people to assay by the Torch method. He also wrote and published manuals. it involves crushing ore, mixing with litharge (Lead oxide) Flux, and borax glass, melting in a charcoal crucible (size of a large briquette) resulting in a lead button, then scorification of the button, and then cupellation of the button under an oxidizing torch flame. resulting in a precious metal bead (or no bead). The bead is measured under an optical comparator (40x pen microscope with a scale in the reticle in increments of 1/1000ths inch). Once measured then I refer to an index of bead size to weight. For instance, a gold bead measuring 20/1000ths inch will weigh 1.63 milligrams. so, if I had an ore charge weight of 1 gram then my assay result would be roughly 58 ounces per ton or 746 milligrams per pound. (very rare to find). It's an involved process and requires practice.

@@myadventure7069 Thank you very much! I use the vibration Sluice that Aussy Bloke Prospector uses for fine gold. I Classify and run equal sizes When Concentrated I dry it out. And put in a large gold pan and shake it all to the bottom. Then I tip the front of the pan up on my lap and Drum quickly with both hands like a drummer would. The overburden rolls back and the crazy fines all come out from underneath. I shake the overburden back to keep room out front for the fines to advance. Once separated, scoop them up with something and then repeat until you have it all. I had been re- fining them over and over i the same lead collector metal. But I frequently burn out crucibles i the fire. A charcoal forge set up. I really didn't know where to go next. I was smelting but my cupelling efforts were laughable. I may have some platinum groups or copper interfering. Always freezing Never completely cupelling. Something with a higher melting point in my way. Thank you for a direction in chemical refining of my fines.. Since my link will be censored I will put it below this post. I love you guys. Thanks for all the help. View from the Penthouse is monday nights about 7:00 central? Hard Rock University. I'm going there now.

Thank you, professor, for your beautiful test, it was very useful and very practical. I had a question, when we heat our solution in the last step, the excess nitric will be eliminated by itself and there is no need for urea anymore. When we use urea, it is possible that the solution go towards alkaline and we can no longer recover gold metal easily. Because urea has its own problems.🙏🏻
@myadventure7069 Жыл бұрын
If you don’t use urea your test can be false.you looking for gold ! For test you need use urea or sulfa mic acide . When you ol redy found the gold then to recover that gold you can do whatever you want.look at my videos where I use two spoons for testing one with nitric and another with no nitric . If you don’t kill the nitric you getting false results
