| abstract |
A method for supercritical fluid extraction of metals from a source, the method comprising: providing a reactor chamber; providing a source containing a target metal; optionally, providing a chelating agent; providing a solvent; adding said source of said chelating agent and said solvent to said reactor chamber; adjusting temperature and pressure in said reactor chamber so that said solvent is heated and compressed above its critical temperature and pressure; Optionally, providing mechanical agitation to the reactor chamber; recovering the chelate comprising the target metal. |
