The eletric arc furnace slag from nickel production (EAF Slag) results from the processing of lateritic ores to produce ferronickel (alloy of nickel and iron). In the third processing step the pre-heated/ pre-reduced feedstock is fed to and electric arc furnace where it is reduced at 1600°C. During this process, a slag phase is separated from the metallic phase. This is the so called EAF Slag. The EAF slag is granulated with seawater and is either dumped or exploited in further steps (1).
