Latest Patents
Crossman's patent, titled "Process for the conversion of molybdenite to molybdenum oxide," outlines a multistep method for recovering molybdic oxide from molybdenite. The process involves several key steps: first, the molybdenite is subjected to pressure oxidation to produce both soluble and insoluble molybdic oxide. Next, the insoluble molybdic oxide undergoes alkaline digestion to convert it into a soluble form, which is then combined with the previously obtained soluble molybdic oxide. Finally, the molybdenum values from the combined streams are extracted into an organic phase using a nonprimary amine. The extracted values are subsequently recovered using aqueous ammonia, resulting in the formation of ammonium dimolybdate (ADM), which is refined through a two-step calcination process.
