Hello All,
In the past, a user named "GUEST" has presented a 17-point theory in this way, and now I feel the need to post a new thread referring to that text, in order to clear up some of the questions I have. For example, the text suggests buying some carbon fabric and placing a one square foot piece of it in a non-fast flowing stream for a week. During this time, the fabric is supposed to adsorb PGMs in the water. the other point is "filtration and precipitation". After the solution has cooled, the coarse particles are filtered out using a coffee filter. Then a substance called T-6 is added to the solution and titrated with acid, during which precipitates containing PGMs are formed. What is "T6" here? Has anyone tested this theory? It seems that ideas and suggestions from senior members of this forum on this subject will be very important for me, the main reason why this subject interests me? There is a geothermally rich area in my city, if this theory is correct, I am thinking of installing carbon fabric traps at critical important points in the geothermal area.
Regards.

1) Go to: http://www.goldmineworld.net/mainmenu.html and order5 square feet of his carbon fabric for $35.; and his 2oz sample bottle of T-6 for $7.50. His web site say the shipping is free.
2) Cut off about 1 square foot of the fabric and tie it to some kind of an anchor with strong wire or string so that you can leave it in a creek for a week without losing it. If the water is very swift try to find a place where the fabric won't bounce against rocks too much. Otherwise you might just find shreds left on your string when you go to retrieve it. The fabric is a very fragile carbon fiber felt. Spring, summer and fall are the best times for this but winter will work if you can manage not to lose it. The best creeks are the ones that are closest to springs and lode bearing mountains, but even a major river should work. There are gold and/or PGM's in all of them.
3) Now boil this piece of fabric in about a gallon of sodium hydroxide and water at PH 11 to 12 for an hour. The liquid should turn a very dark brown from the humic acid being leached. For this initial experiment you can wring the solution out ot the fabric after it cools, wearing rubber gloves and eye protection, of course. This will pretty well trash that piece of fabric in the name of science, but if you decide to go large scale later there are ways to make the fabric last much longer.
4) Filter any sand or debris out with a coffee filter.
5) Stir in 1/2 oz of the T-6 and let it soak for a few minutes.
6) Titrate down with HCl until a lot of precipitate forms. This should be somewhere between about PH 6 and PH 8. Filter that precipitate out and save it.
7) Add another 1/2 oz of T-6 to the liquid and titrate down with HCl again to about PH 1. Let it soak here for a few minutes. Some precipitate may be trying to fall out here too. This is likely to be humic acid that has already been stripped of it's PGM's by the T-6 so just ignore it.
8) Titrate back up to wherever you get the most precipitate again. It will probably be somewhere between PH 7 and PH 9. Filter out the precipitate and add it to what you saved in step 6.
9) Rinse the combined precipitate several times with distilled water in a double coffee filter.
10) Dry the paper coffee filter with the precipitate on it in an old pan at about 225 f.
11) Scrape off as much of the dried precipitate as practical and add it to a suitable clay crucible for smelting at 2000f. (Alternatively, just add the whole paper filter with the material.)
12) GoldmineWorld's suggested house flux is: 40 parts borax, 5 parts soda ash, 1 part flour, 1 part silica sand, and a silver blank as a collector. The suggested hold time at 2000f is 3 hours, but I get very good results at just 1 hour.
13) Pour the melt into a cone shaped mold so that the metals settle in the point at the bottom.
14) After it has cooled break the slag away and weigh the bead. I always lose a lot of silver, probably because my furnace gets too hot, so don't assume that the values you have collected can by determined by weighing the raw bead alone.
15) Part the bead with hot 50% nitric acid to dissolve the silver plus any lead, copper or palladium you might have collected. Drop the Ag and Pd as per the directions on Steve's web site.
16) Treat the solids left over with cold aqua regia to dissolve any gold collected.
17) Now dry and weigh the solids that are left. This is your PGM content, plus, probably, some minor contaminants. Start parting them if you know how. I have seen enough values to definitely look profitable IF the problems I am having now of assaying and selling them can be surmounted. Especially if you can sell the rhodium.
