Effect of modified basicity in selective reduction process of limonitic nickel ore
Journal of Materials Research and Technology, 2021 Basicity is an important parameter in the smelting of nickel laterite to obtain low-temperature melting point and low-liquidus slag viscosity, resulting in less energy consumption and a more effective smelting process ferronickel production. Nevertheless,
