    as 50 grams of molybdenum per hectare will satisfy the needs of most crops. Molybdenum is often present in farmyard manure, in seeds or other planting material such as tubers and corms, and as impurities in some artificial fertilisers. The molybdenum supply from the seed appears to be significant only where the size of the seed is fairly large.

    A spectrographic method has been developed for the determination of 24 trace elements in MoO3. The method is particularly effective for the refractory elements Nb, Ta, Zr, Ti, and V, which are difficult to determine by conventional spectrographic procedures. High sensitivity is achieved in a low amperage arc in argon as a consequence of certain thermochemical reactions which occur in the anode ...

    molybdenum process

    Molybdenum produced as a byproduct of copper from copper porphyry deposits, like the Bingham Canyon deposit in Utah, is removed as molybdenum disulfate during flotation of the powder copper ore. The concentrate is roasted to make molybdic oxide, which can be put through the same sublimation process to produce molybdenum metal.
