Present work reports on the microwave assisted extraction of molybdenum in the form of ammonium molybdate from molybdenum concentrate. In this processing, the ore was heated in air at 750ºC. The process converted the molybdenum sulphides to its oxides and evolved SO₂. Molybdenum oxides were then converted into sodium molybdate which was further changed into calcium molybdate and finally ammonium molybdate using different processes. Hence, the process proved to be efficient and economical for the extraction of high quantity of molybdenum as ammonium molybdate from molybdenum ore. The spectroscopic analysis data revealed that the molybdenite contains 31.2% molybdenum from which 26 % have been extracted in the form of ammonium molybdate. The project is also very valuable because the extraction process is very simple and cost effective as compared to the previously reported processes.
