Thermodynamic analysis of nickel smelting process | SpringerLink

A computer model has been developed to simulate the nickel smelting process. The primary assumption of the model is that six phases in the nickel smelting furnace are in chemical equilibrium. The amounts of all components in matte, slag and gaseous phases under equilibrium are calculated by using the data of free energies of formation and activity coefficients of components. Two nickel sulfide

Nickel and Cobalt Production - ScienceDirect

The first principle of ferronickel smelting is that Ni and Fe oxides are easily reduced to metallic nickel and iron by Reactions and : (2.2.1) C in calcined concentrate + NiO → 800 ° C CO + Ni ° metal (2.2.2) C in calcined concentrate + FeO → 800 ° C CO + Fe ° metal while other oxides, e.g., Al 2 O 3, MgO, are not reduced.This situation arises because oxygen bonds with Al and Mg much

How to Recycle Batteries - Battery University

To some extent, nickel from NiMH can also be recovered economically if available in large quantities. New recycling methods are being developed that retrieve the metals by electrolysis, also knowns as chemical recycling. The process is said to be more cost effective and produces higher yields with less pollutants than traditional smelting.
