A. You'll have to eliminate the nitric acid from the Pd aqua regia solution before precipitating the red Pd salt with Chris Owen- Nevada, Missouri, USA June 25, 2014
A. Vivek, Chris OwenI apologize. I thought you said sodium chlorate instead of sodium formate. Using sodium chlorate is the most common way of dropping Pd. I haven't used sodium formate, but I would think you would still have to remove the nitric first. I may be wrong. - Nevada, Missouri, USA July 18, 2015

A. Dear shaun, bhupesh mulikIf possible, you first concentrate your red colour solution nearly half in quantity by volume. Check the pH, add slowly saturated solution of ammonium chloride in it. You will get yellow precipitate of platinum sponge. cac admixtures - mumbai,india July 23, 2015
Q. Hi, thanks. When you say concentrate I assume you mean heat it up so some of it boils away -- how do I find the pH of what's left? This yellow sponge. Do I then heat this up and turn it into a platinum ingot
shaun claremont [returning]- croydon, surrey, england July 26, 2015
A. Dear Shaun, bhupesh mulikYou have a solution which contains Pt. You heat this solution nearly half meaning if you have 4 liter solution, concentrate by boiling & make up to 2 liters.

Q. I was having some amount of palladium on carbon 10% powder and I wanted to take palladium out of carbon powder so I made aqua Regia solution with HCl and HNO3 at ratio of 3:1 and put the palladium carbon powder in my aqua Regia solution and boiled it for 30 mins and more and after filtration I got very dark brown or dark red solution and I tried to precipitate palladium with the help of sodium metabisulphite, but it doesn't work and my solution is still in same color and it's been 2 days I have kept it in a borosil beaker. Imran ChoudharySo please anyone experience person who can suggest me that how can I precipitate palladium out of my aqua Regia solution with which other types of chemicals and how?

Q. Hi my name is Mark; I'm a small miner in Arizona and have achieved a separation of palladium and have converted it to palladium oxide at 1800 °F and now I'm trying to smelt in my induction furnace but cannot achieve above 400 °F with the oxide. The induction furnace will achieve 3800 °F according to manufacturer. I've seen the process done on youtube but they don't show how they started the melting process, just kept adding more oxide into the melt. Does anyone have knowledge of why the furnace is not harmonized for the oxide?

Q. Hi Bhupesh, Armaan Joshi [returning]I do XRF to check the same. I doubt if ammonium chloride is precipitating some palladium or XRF is interpreting something false.
