Molybdenum and tungsten can be extracted with alkylamines from acidic solutions obtained during the chemical refinement of scheelite concentrate at the Tyrnyauz Processing Plant. These solutions contain 5-8 g/l of molybdenum and tungsten. Each is present in both oxidized and reduced forms. The solution also contains significant amounts of phosphorus and silicon. Apparently, molybdenum and tungsten are found in these solutions in the form of phosphoric and silicic heteropoly acids, since these metals are excellently extracted by solutions of amines in nonpolar diluents. To determine the state of molybdenum and tungsten in these solutions, the behavior of metals during extraction by their amines from hydrochloric acid solutions in the presence of phosphorus and silicon in a wide range of hydrochloric acid concentrations was studied...
