Here's where I'm at, I work for a rhenium recycling plant. At the end of our process we have 54000L or so this mother liquor that contains about 3g/L of rhenium as ammonium perrhenate. I have a few options I am considering to try but only have limited knowledge about rhenium because I have only been here a few months. I am open to any suggestions anyone might have because it is soon to be disposed of as waste and there is potentially $1mil worth of product tied up in these things.
Thanks
Mac
