This is the colour after about a week in the solutionI do have copper sulfate but I didn't want to complicate the mix as was trying to keep as clean as possible.

This is black sands concentrate?This is the colour after about a week in the solution
Lead will not cement on Copper.Also I used copper to try my cementation. Closer to reactivity that gold and silver. Didn't want copper to come out of solution but exchange leaving gold silver and lead.
It drops out if in solution correct?Lead will not cement on Copper.
Only PMs and Mercury.
No, lead will stay in solution until you add a few drops of Sulfuric acid.It drops out if in solution correct?
Well dang. That's good to know. I though it I would have to cupel it after melting but shouldn't have to. Thanks for sharing.No, lead will stay in solution until you add a few drops of Sulfuric acid.
Don't you have a copy of the reactivity series of metals?Well dang. That's good to know. I though it I would have to cupel it after melting but shouldn't have to. Thanks for sharing.
Ya. I was thinking lead was below copper. My mistake.Don't you have a copy of the reactivity series of metals?
You will find it in here or on Google.
Hi, Yes this is black sands concentrate correct. Run from my shaker. I'm wanting to use this up/test before I start on my ore. I have about 15 buckets of nice looking sulfide ore once I get this sortedThis is black sands concentrate?
Hi there, how would you know when the Thiosulfate has been consumed by the copper sulfate and then I guess you would just add more thiosulfate to the mix. It's like I'm the mad professor. A pinch of this, a few drops of that. There must be a correct formula out there I have had a read but alot is over my head when they start with chemistry formulas ect.Sulfate is add it to sodium Thiosulfate leach for gold ore
it will help to lower the consume of thiosulfate
but adding too much Sulfate will have a negative effect in the gold leaching .
the formula is simple but .
i don’t have the formula.
cooper sulfate is adding because with 25%-30% ammonia will be a strong Oxidizer
Becareful with Ammonia Fumes can be deadly
tempeture is key in the leaching process
keeping like at 50 F
will help a lot to leaching out the gold from the Ore.
Ore granulation ,for me work better at 200 mesh.
Precipitation
can use Zinc,Iron sulfate
There is a formula. Will find it and post laterHi there, how would you know when the Thiosulfate has been consumed by the copper sulfate and then I guess you would just add more thiosulfate to the mix.
