Rhenium Raw Materials Sources
Rhenium is a typical scattering element. It does not form independent
minerals. Rhenium in the earth's crust weighs 10B-7%. Accumulation of
rhenium was observed in granite pegmatites and aerosol formations. High
levels of rhenium, especially in molybdate, were observed in compounds
in Colombia, Tango, and Alvite (Alvite), as well as in alvite and Elby
regions (Torviti, gadolinium).
The relationship with molybdenum is determined by the isomorphism of
Mos2 and ReS2, and the ionic radius is Mo4+=0.68A, and Re4+=0.56A.
The range of molybdenum content in different deposits is 10B-2-10b-5%.
However, the samples found contained a tenth of rhenium. The Lynayaur
mine in northern Sweden, for example, contains 0.25 per cent rhenium in
molybdate.
A molybdenum deposit containing copper shale in Mansfield was found to
contain 0.01 per cent of rhenium.
At present, the major sources of plutonium are molybdenum and copper
molybdenum, which includes ores containing molybdenum in amounts that
are not of industrial significance.
In the processing of ore raw materials, a variety of production wastes
are concentrated as a source of recovery.
