I am needing some clarification on processing wastes-
I have looked at 4 Nines excellent post on this in the Library but would like to know a bit more on this-
From parting inquartated gold ( kt gold/silver added, not kt gold /copper added ) with Nitric - I end up with Silver Nitrate =
1. Some of the silver nitrate I have I cemented the silver out with Copper- I have this solution in a sealed bucket that I now need to add iron inorder to drop out the copper and other metals which may be in there0
2. a. I have some silver nitrate that I used HCL to get silver chloride out. I then used copper and then used Iron to drop out the metals- I have a beaker of it which I only put the iron in and now its a greenish solution with the crud copper on the bottom-
2.b. In a pail I have the same solution as in 2.a. however I used an air bubbler and now the solution after the air and iron is a muddy copper or rust color- Its show in the image in a white pail.
My questions are :
When you are at the final step of waste- do you need to put an air bubbler in with the iron or not ?
When you add iron- from reading 4 nines post the PH of the solution should be 2.5 before adding the iron -
How do you determine if the iron has completed what its meant to do ?
After the iron has done its job- do you add lye or lime to the solution with the cemented out metals in the bottom of the bucket to raise the PH to 10 -
or do you have to siphon off the solution from the sludge of metals and then adjust the PH ?
If you do have to siphon off the solution from the metal sludge what do you do to treat the metal sludge ?
Also- is the copper and metal sludge at the end of this process safer to toss out or does it need to be treated or dealt with some way to make it safe ?
and my last question- it seems like if one were trying to use the copper from the iron drop that most folks here consider it a lot of work for little return - if this is not correct what would be the proper way to get the copper out so you could use it or melt it into a usable metal of sorts-
Thank you all in advance- I learn so much from here and I appreciate all the sharing -
