Advances and Innovations in Ferronickel-Making (eBook)

This book introduces the most inspiring progress in the production of ferronickel from laterite ores, from both theoretical and technological perspectives. Based on a detailed overview of nickel utilization from laterite ores, it provides the advances of four main methods for laterite ore processing, including the solid-sate reduction-magnetic separation process, the rotary kiln reduction-electric arc furnace smelting process, the Krupp-Renn process, and the sintering-blast furnace smelting process. Moreover, for mediating the adverse impacts of the byproducts in ferronickel and subsequent stainless-steel making, it presents pioneering technologies of utilization of ferronickel slag for producing value-added functional materials and recycling of stainless-steel pickling sludge for ferronickel making. This book is expected to offer the audiences a fascinating new insight into ferronickel making and related by-products valorization.
