Enhanced Chromium Recovery in the Smelting of Ferronickel Along with Energy-Saving: An Industrial Case Study

The rotary kiln-electric furnace process accounts for two-thirds of the global nickel output. The raw laterite nickel ore contains approximately 1–5 wt.% Cr 2 O 3 , but its recovery is limited during smelting. Due to the inefficient utilization, the accumulated Cr-containing slags are potential envi...
