Scandium extraction from silicates by hydrometallurgical process at normal pressure and temperature
Journal of Materials Research and Technology, 2020 Silicate is an important rock-forming mineral. In this work, a method called “sulfuric acid curing” was proposed, aiming to extract rare earth element scandium from silicates.
