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
To produce this much rhenium we need to extract about 4.1 million kg of copper ore from the ground, which costs an estimated 140,000kg of carbon dioxide (CO2) in mining and refining the ore. Compared with a rhenium-free turbine, the other production costs are assumed to be roughly the same (this of course is an over-simplification as a ...

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. The recovery of rhenium is aided by the concentration of its volatile heptoxide (Re 2 O 7) in the flue dust and gases given off during the smelting of molybdenite ore or from its concentration with the platinum metals in the anode sludge …

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.
