Thermochemistry of Nickel-Matte Converting

Pages 285-298 | Published online: 29 Nov 2013
 

Abstract

Newly developed mathematical correlations of the thermodynamic properties of melts in the systems Ni–O, Ni–O–S and Ni–Fe–O–SiO2–CaO are presented. These correlations, along with new measurements of activities in the ternary Ni–Fe–S, are used to explain the behavior in conventional converting of iron-nickel mattes, in the proposed process for converting sulfur-deficient iron-nickel matte without evolution of sulfur dioxide, and in the converting of nickel sulfide to metal.
