Abstract

Nickel is mainly used as ferronickel in stainless steel production industry. Its usage as low grade ferronickel or nickel pig iron (NPI) in stainless steel production is a relatively new trend to reduce the cost of high grade ferronickel. In this study, low grade lateritic nickel ores were processed by using carbothermal reduction to produce NPI. The used ore was from Turkey East Anatolian region. In the first experimental set, raw lateritic ore containing 0.9% Ni, 0.054% Co and 2.3% Cr was mixed with metallurgical grade coke at different stoichiometric ratios. The samples were smelted at 1600-1650 °C temperature range in an induction furnace for 25 minutes. In the second experimental set, different process times were examined varying from 15 to 35 minutes. The effect of CaO addition to the smelting charge was also investigated in the last experimental set. Raw materials, obtained alloy and slag phases were characterized by using XRD (X-Ray Diffractometer), XRF (X-Ray Fluorescence Spectrometer) and AAS (Atomic Absorption Spectrometer) techniques.
