Minerals | Free Full-Text | The Distribution, Character, and Rhenium

The distribution, character, and rhenium concentration of molybdenite within the two investigated ore bodies seems to be related to specific alteration and vein features rather than to rock types, and these features also seem to have an impact on the final recovery of molybdenum.

What's Rhenium Doing in a Jet Engine? | Science Features

Rhenium | Chemical Element, Alloying Agent | Britannica

Rhenium occurs up to about 20 parts per million in molybdenite and to a lesser extent in sulfidic copper ores.

9 Ore Deposits and Economic Minerals – Mineralogy

The best metal ore minerals are those that contain large amounts of metals of value. Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, and sedimentary.
