title = "Selective precipitation of magnetite in copper slag by controlled molten oxidation",
abstract = "Molten oxidation is a sustainable process for direct precipitation of magnetite from melt copper smelter slag because it involves zero or less energy input due to the exothermic reaction and free reducing carbon addition. During molten oxidation, magnetite precipitation occurred preferentially because of its intensive ferromagnetism and large crystal size, which enables downstream magnetic separation. Previous milligram-scale experiments conducted using an infrared furnace show that magnetite could be precipitated, while precipitation of hematite was limited under an atmosphere of 1 vol% oxygen. In this study, gram-scale experiments were conducted using an electric furnace to verify larger-scale molten oxidation at 1 vol% oxygen.",
