this is a great method, i am using this method and getting gold on daily basis, but i am using 2.5 volt and 6 ampere with iron nail on both terminal as your old video showed, thanks a lot for too much easy method
I do this method but backwards my machine told me the cords were backward so i switched them. There was very little happening when i had the connections on either way. so i remembered when I used epson salt to remove silver plating you needed a catalyst so i put smb as the catalyst and the gold started coming out in sponge form.
Great method. I've used stannous chloride, and the first, solutions is changed the clear, and after, the precipitation shall be conducted (about from 20 to 30 minutes), it is more quickly if a little heating for the solution but is not over 50 Celsius degrees. By XRF machine, I've find the metal mixture powder with 10% gold, 21% copper and PGMs remain. So, gold is still in solution, however, the colors of mother solution have not changed the black or other colour, It is only to change the clear color at the first. What do you think about this matter.
@@myadventure7069 Since you're applying voltage , why not displace the gold with copper? Wikipedias' "Reactivity series of metals" states there are many other metals between iron to copper that might get in the way. Oh , And if you just tie the iron and copper wire together , wont it form a sort of galvanic cell so you dont even need to add DC ?
Copper is less reactive than iron, and will only precipitate silver, gold, and PGM. If you treat the ore/rock/material with nitric before hand, there’s a good chance you’ll remove all the copper before dissolving the gold. Unless it’s an alloy of gold that has more than 50% gold. Also, it’s hard to get gold into solution if copper or other metals are present (remember, it drops gold). The solution will just sit there and cycle, leaving the gold behind. Lastly, Iron is easier to separate and remove than copper is. Magnets, HCl, H2SO4, etc. hope this helps :)
