Hey Guys
I have just got more involved in the parting area in work and I am questioning the method that we use. Seems a bit overkill to the methods I have found on the Internet and in books.
We start it off in cold 1-7 nitric acid in porcelain crucibles on a hot plate @ 200oC. This is left to simmer until the reaction ceases. We then top up with 50% nitric and evaporate to half the volume.
Then we decant off the solution, wash with pure water and then put back on the hot plate in full 50%. Reduce volume to half again. Decant off and then wash 3 times.
Just wondering what method(s) everyone else uses?
