Abstract:
In this study, nickel pig iron alloys were synthesized by carbothermal reduction of lateritic nickel ores obtained from west Anatolion region of Turkiye. At the beginning of the study, the calcination process was applied on the lateritic ore which is containing 1.58 wt. % Ni and 0.12 wt. % Co by using in a semi-pilot scale rotary furnace at 1100 °C for 1 hour. Then, a mixture of calcined ore and metallurgical grade charcoal was prepared and charged into a sintered alumina crucible. Carbothermal processes were carried out by using a graphite resistance tube furnace at different time (0- 60 min) and temperature (1450-1600 °C) under inert argon atmosphere. The raw materials, alloys and slags were characterized by using wet chemical analyses, XRD (X-Ray Diffractometry), and EPMA (Electron Probe Micro Analyzer) techniques.
