Hey prof. Long read bare with me. I had never precipitated with aluminum I tried it today. I had some crushed up rocks I saw microscopic gold on. Small sample of powder. First I used HCL boiled for a while. Let cool. Washed material thoroughly. Next, weak AR. My solution turned orange red. Cooled for a little. Denoxed. Dropped aluminum. After a while solution turned swamp green like brown dirty yellow green. There was some reddish brown precipitant at the bottom and some black floating at top. Maybe tin. After decanted and washed several times with water. then thinking the precipitant was gold I did some hot HCL wash and everything dissolved. Solution turned bright yellow. Defeated I tested with scl just in case maybe some leftover AR got activated even tho I rinsed several times. got a big fat negative. Solution turned clear 😂 What was that reddish\brown precipitant if not gold…iron? I’m confused. How can it be iron if I rinsed after HCL boils? Did the HCL not get rid of base metals (iron) and the AR dissolved into solution and then the aluminum precipitated them? I’m going to try it with precipitating with zinc next. Maybe I was betrayed by my eyes and rocks have no gold..
You must see brown that is gold color . Aluminum drops all the metals . In solution must be plenty HCL then no airon and another basic metals precipitates .
Great channel.. I use a electric demolition hammer with a 5 cm round piece of iron welded on the end instead of the the tip for crushing the rocks goes verry fast for small potions 4-5kg.. If you have 0,5 gram on 10kg you have 50gram pr ton... Defently enough to buy or make a small hammer mill for processing.. And then run it through a centrifuge so you only have a couple of kilos you need to proces with aqua regia.

ok there is a reason why I don’t like alluminum, because it is hard to get .9999 with it. if even a fraction of it is left in the gold it makes the gold kinda brittle and the jewelers don’t like to work with it , that’s if your customers are jewlers they are fussy and wont pay as much unless it is .9999 which takes multiple refinings, with aluminum what you save in cost for precipitation you end up spending in hydrochloric for multiple refinings that are needed. lemme just say also weak aqua regia better than regular aqua regia to get gold from rocks. this is an easier better way but there are in fact even better and weaker acids and methods that are much easier to
another thing too. if you bath the ore in hydrochloric first to clean consider there are some pgms in a salt form that dissolve in the HCl so dont throw this you can actually precipitate from it noble metals still
Yes is best think is cianide ! But I can’t buy it noubody sells it to me .Week aquaregia is just for invisible gold if you pan it and see gold don’t use week aquaregia till you remove all that visible gold
I try all methods to recover that gold I getting redy go to electrolysis but problem is in my ore is a lot different metals I trying to to separate them all elektrolisis don’t do that
Excellent video. Did you use KNO3 to make the nitric acid? I agree that Aluminum makes very small particles that can be hard to filter. Your rocks are very rich in gold! Congratulations! -- Dave
That kino rocks is ewriwhere he but they don’t have visible gold that why nobody collects them . I using KNO3 I don’t use nitric acide. Need get sodium cyanid for this gold ore .Gold is ewriwhere but my problem is am to old to work with big gold .In those rocks is a lot invisible gold and another PM .
Great progress….For your aluminum, you used a piece of aluminum siding? I wanna try aluminum like you do, but is it okay if it’s not all aluminum. I suppose it would be okay if it’s both aluminum and zinc mixture, since you precipitate the gold with both metals, anyway. I might try a piece of aluminum siding, to see how it goes. I don’t have any old electronics around the house. I’ve been using the stannous and smb, so far. Thank you, for another interesting video. Your road is getting stronger, and stronger..😊
I chalenge you to try to melt that gold you have precipitated with alluminium. Almost impossíble. Very dirt gold. I've used alluminium so many times. Whashed the gold with hot water and hcl many times. Still almost impossible to melt.
Aluminium Chloride is yellow, as well as Iron Chloride. If you use Zinc metal it is much cheaper. Those zinc roofing planks are a great source of zinc, also inexpensive. Maybe US$10 for a whole plank, it can last you months 😂 or maybe years. Also it will be a clear solution once you precipitate using the zinc
