Abstract

The effect of machining conditions on the scandium leaching effectiveness from the wastes of wet magnetic separation of iron–titanium magnetites in sulfuric acid solution has been studied. It has been shown that the degree of recovery of scandium into sulfuric acid solution linearly increases with an increase in the degree of amorphization of specimens of wastes of wet magnetic separation.
