01/12/2019  The diluted solution was added to the leach liquor in 2–10 vol% of the total volume. As can be seen, at the early stages, the precipitate volume and recovery percentage of molybdenum increases simultaneously with increasing the CPE value ( Fig. 1 ). By exceeding the 7.2 vol%, phase separation encounters a problem.

Leaching with caustic soda is efficient for low concentrations of plant catalyst and allows recovery of molybdenum as trioxide, and vanadium as pentoxide. Under selected experimental conditions, i.e. leaching at room temperature the spent catalyst needs to be leached with 20% NaOH solution to form soluble vanadium and molybdenum compounds and it is easy to recovery of oxides. wt% caustic

Molybdenum is recovered from dilute, ammoniacal, molybdenum containing solutions by adding ferrous ions to the solution to precipitate an iron hydroxide-ammonium molybdate complex. The precipitate is separated from the aqueous raffinate and is treated with acid to resolubilize the molybdenum in the complex. Molybdenum values are recovered from the resulting acid solution by
