Nickel pig iron production from lateritic nickel ores - Pyro.zaJun 9, 2013 . Ferronickel smelting of lateritic ores is generally performed by using fossil fuels (coal, oil, natural gas, etc.) as a reductant in a rotary kiln. Nickel and cobalt are firstly reduced because iron has greater affinity to oxygen. The product is charged to converter for refining after discarding the slag phase containing.A Pilot-plant Scale Test of Coal-based Rotary Kiln . - ProgramMasterAbstract Scope, Nickel pig iron (NPI), used as a substitute for electrolytic nickel, is able to reduce the production cost of stainless steel greatly. Aiming for preparing NPI from nickeliferous laterite ore, a pilot-plant scale test of coal-based rotary kiln direct reduction of laterite ore was performed and reported in this study.
