What to do with all your leftover concentrates? Ever try "roasting" it to get more gold maybe?? Roasting is a technique of heating up the sulfide ore to a high temperature. This breaks the sulfide to an oxide and more metallic particles are released. Anyway, this was a rudimentary testing of that process on some of my North Saskatchewan River concentrates. Please take proper safety precautions if performing this task as it can release harmful gas into the environment.
See you out there!

I don’t process without roasting anymore. Throwing it into cold water while hot helps a lot. It cracks the varnish stuck to the gold and releases it. Good video.

So when you're roasting sul fides what happens is tiny molecules of water and oxygen burst from the insides of the sulfides to the outsides and break holes in it that's what releases the tiny particles of gold It's just like oxidized coal the water just burrows holes microscopic holes and it and just tears it to pieces and gives it much much more surface area same process with sulfidolphins oxidization is Wanted outcome

Just a quick suggestion; ... after aprox. 30 mins of roasting the cons at aprox. 1,000f - dump them in cold water ... this will shock the black sand and turn them brittle ... then take the brittle cons and subject them to a light crush ... then run thru Miller Table

I have been observing people go through a lot of trouble getting the flour gold. In Lab I would use a centrifuge to concentrate it. and if there are platinum group metals they will concentrate too. With heaviest at bottom and lightest at top. Will even stratify into layers.

I don’t know if you planned on doing a video on it, but I’d personally like to see it. It would be interesting to see if it recovers enough to warrant doing. I’m guessing yes. Super easy do have them in a pan and just toss it on at the end of the night.

@highenergyog 4 жыл бұрын

Its a beautiful thing watching the sands separate from the sulfides separating from the gold on your Millar Table , have you ever thought of selling paydirt or paysands ? I'd love to try panning some North Saskatchewan River blacksand , i finally had the chance to pan about a month ago but sadly my house was broken into while I was at work and they took my 0.03 grms gold along with my sons video system and a few more items of value. And yes they got my metal detector that had the sticker you sent me a year ago on it , probably drug addicts. Stay safe out there , best regards as always from Lloyd somewhere here in Southern Ontario Canada 🇨🇦..

Heat is the chemical process as it releases the (loose) molecular bond in the sulphides.

I thought you throw that out into the garden and let it grow into bigger gold . Why does the miller table work ? does it have a lot to do with the weight and shape of the material . as NSR gold is flat as apposed to the blonds and Black sands that are more rounded . The blonds are first out because they are lighter than the black?

The problem with trying to mechanically separate gold from black sand is that it is a fools errand. You see only 15 to 20 percent can be seen with 20-20 vision!!! The other 80% is below visual level, microscopic. Every thing below 100 mesh just can't be seen, but the gold goes down to 300 mesh!!!!! You have to use amalgamation to get it all out!!! Get you some mercury and a rock tumbler and learn how to recover 100% of your mercury, either by retort or nitric acid and a small bottle of quicksilver will last indefinitely. Both Jeff Williams and Two Toes have excellent videos on amalgamation. Till you do, you will continue to throw away 80% of your gold!!!! A Miller table or a blue bowl are excellent if your intent is to throw away the 80% and keep 20% ;) Those of us that are greedy enough to want the whole 100% got rid of such a long time ago!!

Without a closed loop recirculator pump system with 'jetdry' the water surface tension floated the gold off the table and most likely out of the pan ... Your choice your loss so either 100% best effort or sloppy technique for whatever falls... Good luck!
