Chemical Equations For Gold Extraction

  • extraction, liquid liquid

    liquid liquid (or solvent) extraction is a countercurrent separation process for isolating the constituents of a liquid mixture. in its simplest form, this involves the extraction of a solute from a binary solution by bringing it into contact with a second immiscible solvent in which the solute is soluble.
