Chapter 2 Occurrence and extraction - ScienceDirect

1999-1-1  11 CHAPTER 2 OCCURRENCE AND EXTRACTION 2.1 OCCURRENCE Molybdenum disulphide occurs naturally in very large quantities as the mineral molybdenite. Because of this ready availability, there is little incentive to develop any alternative sources, but small amounts have been produced synthetically, and the synthetic processes will be described later.
