Smelting of low-grade saprolitic nickel ore in DC-arc furnace [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2023
Most nickel laterite smelting to produce ferronickel is carried out using an AC-arc furnace. Although the DC-arc furnace is advantageous in the smelting of fine ore, it is rarely used for nickel laterite.
