Porphyry Copper, Gold, and Molybdenum Deposits: Preface ...

The ore deposit is a porphyry type, similar to many large copper deposits, where many intersecting small veins of molybdenite form a stockwork in an altered quartz monzonite porphyry.Like other porphyry-type ore deposits, the ore is low-grade, much less than one percent molybdenum, but the ore bodies are very large.

Because pure molybdenum melts at such a high temperature and because it oxidizes at relatively low temperatures, traditional smelting processes cannot extract the metal from its ore. Instead, ore is processed in a series of grinding and separation steps to isolate its MoS2 (molybdenum disulfide) from other components. This isolated material,
