Amines molybdenum complexes, solvent extraction

Another important technology for the concentration and winning of minerals and metals is solvent extraction. Up to the time of writing there is only one area where RR-based chemicals are used commercially. Tertiary amines (- fatty amines) with short- to medium-length alkyl chains and their - quatenary derivatives form ion pair complexes with certain metals that are dissolved in an aqueous medium. These reagents are widely used for the recovery of uranium, vanadium, nickel and, to a lesser extent, molybdenum.
