A Guide To Machining Molybdenum Metal and Alloys
Drilling, Tapping and Threading. Molybdenum can be drilled with high speed steel drills. However, carbide drills are recommended for deep drilling. When using high speed steel drills, the speed should be 30 to 50 feet per minute with a feed of .003 i.p.r. Cutting oils should be used for all tapping, drilling and threading operations.

Rhenium is widely spread through the Earth's crust at approximately 1 ppb. Chile has the world's largest reserves and was the leading producer as of 2005. Commercial rhenium is extracted from molybdenum roaster-flue gas obtained from copper-sulfide ores. Some molybdenum ores contain 0.002% to 0.2% rhenium.

Due to their redox-sensitive nature, the geochemical cycles of Re and Mo are linked to the global organic carbon cycle. Reducing sediments constitute a globally important sink and weathering of organic-rich sediments is responsible for a large portion of the Re and - to a lesser extent - Mo flux to the oceans (Colodner et al., 1993; Jaffe et al., 2002). Riverine concentrations of Re and …
