Rhenium metal production

Production

The production of rhenium begins with the extraction and concentration of copper sulfide and molybdenum ores. The main problem here is the low concentration of this element. According to general information about rhenium, the largest deposits are located in the USA and Chile. At an annual consumption rate of 45−50 tons, mankind has enough world reserves of this metal for almost 300 years, not taking into account recycling. Rhenium is smelted using pyrometallurgical methods (conversion, smelting, and oxidative firing). During roasting, rhenium oxides are sublimed and then trapped by trapping filters. Part of the rhenium is retained in the ash, from which it is transferred to soda or ammonia solutions, from which the metal is later recovered by hydrogen. During smelting of copper concentrates, up to 60% of Re is volatilized with smoke. During processing of copper concentrates sulfuric wash acid becomes the main source for extraction of this metal.

Technical Characteristics

Pure rhenium is much more ductile than tungsten. It can be rolled and drawn into fine wire under normal conditions. The «rhenium effect» was also discovered: it was found that this metal increases both the strength and ductility of molybdenum and tungsten. Because of its high modulus of elasticity, the hardness of rhenium increases significantly after machining due to accretion. To restore ductility, it is annealed in hydrogen, vacuum or inert gas.
