A method of recovering rhenium from rhenium-containing superalloy scrap is provided. The superalloy is usually a nickel-based superalloy. The method includes the steps of forming an oxidation feedstock of flaky morphology of the superalloy scrap, and oxidizing the oxidation feedstock to convert rhenium into a volatile rhenium oxide. The flaky morphology of the oxidation feedstock is achieved by increasing the surface area of the superalloy scrap.
