Osmiridium Ore

[TransitionM]

Does anyone know how to safely process/refine Osmiridium/Ruthenium ore? It's in chromite.

At 100°C, sodium hypochlorite will dissolve ruthenium, and for osmium at the same temperature, phosphoric acid should be used. To precipitate the metals in the liquid solution, zinc should be employed, followed by the use of HCl to eliminate zinc. This is just a suggestion; you must adhere to maximum laboratory safety measures, as failure to do so may lead to serious consequences. Best regards and good luck

Be very careful with osmium, its compounds, OsO4, are very dangerous.

If you do not have properly equipped and working lab, your best shot would be to sell it as is.

Do not attempt to refine anything that has ruthenium or osmium, this is no joke. If you do not precisely know how to do it safely and do not have broad experience with advanced chemistry... Better to be safe.

Vaporized Ru/Os will contamine all the surroundings, if not properly scrubbed.
