Collectible minerals - full range in stock "Molybdenite"

Molybdenite (molybdenum pyrite) is a mineral found in granites, greisens, quartz veins, and sometimes in pegmatites. It is the main raw material for the production of molybdenum. In the form of impurities, it may contain selenium and rhenium, which are also mined from molybdenite. It is a semiconductor. Due to this property, it is used in the radio-electronic industry. It is also used for the production of lubricants.

You can see molybdenite stone for sale and buy it in the Minerals of Russia online store.
