Recovery Rhenium from roasted dust through super Para-magnetic Nano-particles

Thermo‐responsive ReO4− composite membranes with SiO2 modified: Preparation, performances and application in secondary resources

“…7,8 Because of the limited number of products that can be substituted for Re, the high cost of substitutes and the excessive performance loss of substituted products, Re is expensive, which varying between 2600 US$ per kilogram for NH 4 ReO 4 and increasing annually. 9,10 With the growth of industrial demand, Re is not only the amount of price growth, but also accompanied by the conflict between supply and demand. Recovery of Re from rhenium-containing secondary resources is an effective way to solve this problem.…”

Solvent Extraction of Rhenium Using Lipophilic N235 in the Hydrophobic Room-Temperature Ionic Liquid

“…This method only needs simple equipment and always performs at room temperature or low temperature, with a simple operation process. This method is suitable for mass production, which plays an important role in industry development and environment protection. − …”

Extraction of Re(VII) from Hydrochloric Acid Solution with TiOA in Hydrophobic Ionic Liquid

“…As one of the most rare metals, the quantity of rhenium is very small in nature, and a single rhenium mineral has not been found so far; it is mainly scattered in molybdenite and bornite. Rhenium and its alloys have common application prospects in petrochemical, aerospace, metallurgy, defense, and other industries because of its unique physical and chemical properties of high melting point, excellent ductility, formability, high density, catalytic activities, and so on, so it is in short supply in the market. − …”
