I work in a hydrometallurgical process development lab. Last year, an environment organization from the other shore of Lake Ontario informed that they found metal-contaminated streams over the bottom of the lake down into their shore.
Since then I have been thinking about a non-aqueous leaching approach for valuable metals, like nickel and cobalt. The leaching medium will be water-clear phosphorous oxychloride. However, here a big challenge to me is that I am lab assistant. I pounded the pavement for 10 months before getting this job. I worry presenting an iffy proposal will likely result in losing job. I hope some of you would be so kind as to verify the following designed reaction for me by searching SciFinder Scholar or doing experiment if necessary:
Its succedent separation procedures won't scare me. For example, from previous working experience I know Cl(POOCl)nPOCl2 is a kind of low-melting-point glass and that this glass-like polymer can be recovered to manufacture extractant DEHP or something else, like semi-liquid 2-in-1 phosphating & saponifying lubricant for cold extruding of steel rod.
In presence of excess POCl3 medium, FeCl2 / FeCl3 / MnCl2 / MgCl2 are expected staying with ore residue, whereas NiCl2 and CoCl2 are expected staying with Cl(POOCl)nPOCl2 in the same liquid phase, because of complex formation.
After excess POCl3 is evaporated, NiCl2 and CoCl2 are expected to be able to precipitate in the liquid melt of Cl(POOCl)nPOCl2.
