Rhenium is utilized as an additive to improve the high-temperature strength and stability of materials, such as nickel-based superalloys, which are employed in jet engine turbine blades, alloys for ultrahigh-temperature thermocouples, and platinum catalysts, which are used in oil refining. Currently, around 80% of rhenium demand is for superalloy production, and this demand has been increasing with the increase in demand for aircrafts. The abundance of rhenium in the earth's crust is only 1 ppb (10−9), which is less than those of platinum and gold. Owing to the rare and unevenly distributed nature of rhenium, there is the risk of supply disruption and rapid increases in its price. In this article, the recent situation of rhenium and its compounds are reviewed, especially with respect to their demand, distribution characteristics, smelting, and recycling. Some of the technologies recently developed for smelting and recycling rhenium are also introduced.

“…Традиционная пирометаллургическая переработка сплавов на основе вольфрама малопригодна к ренийсодержащим материалам из-за потерь чрезвычайно ценного рения [9], в связи с чем создание технологических схем переработки ренийсодержащих вольфрамовых сплавов, основанных на гидрометаллургических процессах, в полной мере отвечает целям увеличения эффективности рециклирования ценных компонентов и повышения экологической безопасности производства. Применительно к трудноизмельчаемым вольфрам-рениевым сплавам целесообразно использовать электрохимические методы, отличающиеся универсальностью, связанной с возможностью перерабатывать техногенные отходы вне зависимости от их формы и крупности [3,10].…”

The electrochemical behavior of rhenium-containing tungsten alloys waste of the type WRe (wt. %: W — 80–95, Re — 5–20) in a solution of (NH4)2CO3 1,0 M was studied using the method of linear voltammetry in potentiodynamic mode and potentiostatic electrolysis. Separation of tungsten and rhenium from the resulting electrolyte was carried out by crystallization of ammonium paratungstate and concentration of rhenium in the mother liquor. A basic technological scheme for the processing of rhenium-containing tungsten alloys is proposed.
