Oil shale
There are large deposits of molybdenite in the USA, China, Norway, Germany, Mexico, Republic of Korea, Bolivia, Peru, Chile, Armenia, Kazakhstan, Poland, Russia, Uzbekistan, and other countries.
CLASSIFICATION OF MINERALS CONTAINING RHENIUM
NATIVE ELEMENTS and ALLOYS: Rhenium
SULFIDES and SULFOSALTS: Rheniite, Tarkianite, Dzhezkazganite, Molybdenite, Pyrite
OXIDES: Columbite, Pyrolusite, Tantalite, Kipushite
SILICATES: Zircon, Alvite, Gadolinite
SELECTION OF METHODS FOR SEPARATING OF RHENIUM MINERALS
During the processing of minerals containing rhenium, plants use the following types of separation:
Rhenium is mainly obtained as a by-product of the extraction and refinement of molybdenum and copper ores.
The main source of rhenium is molybdenum concentrates (rhenium content 0.01-0.04%; 2-20 to 200-300 g /t).
Currently, the industrial source of rhenium is also the waste water of hydrometallurgical processing of poor molybdenite concentrates. Industrial waters contain between 10 and 50% rhenium.?
