Hi guys, I got a bag of 5 grams of pulverisation or grind ( or whatever the correct English word is) from a jeweler to process. The powder consist for the biggest part of silver (fine and sterling I think) and 14k gold. And then there is a part that I suspect to be Iron pulverisation and a little tiny bit of a nickel alloy because my magnet reacts to a small portion of the bulk. Another part of the bulk, also very small, consist of sand and plastic pulverisation.
So we have a bag that consists of:
14k gold and up
Fine silver and sterling
Iron
Sand and plastic
All of this pulverised together.
There are different ways to refine this of course, but I am searching the smartest, less time consuming and cheapest way.
Ok, this is how I think of doing this:
First, remove the Iron and nickel alloy using a magnet (like processing flatpacks in partnor's method) and store as low yield gold scrap for later processing.
Second, incinerate the left over bulk to get rid of all carbon consisting components like plastics.
Then, inquart the left over bulk so that it can be dissolved in AR. And follow the well known process of filtering precipitating and washing.
In this last step there is still sand in the bulk, I am not sure what it will do when I inquart, but from the acids I suspect no problems because siliciumdioxide will not react as it is the main component of glass.
Another approach of doing the refinement is to remove the Iron as said, but to just pan the remaining bulk out. The seperaition is then done by difference in density...
What do you guys think??
