SYNOPSIS

This paper reviews the development and suitability of various important thermophysical and electrical properties with respect to base metal mattes. Areas of focus include the critical validation of measurements of viscosity, density, surface and interfacial tension, electrical conductivity, and an overview of the various experimental methods used to determine these properties. Accurate physical property data of mattes are critical in process modelling and computational fluid dynamic modelling of smelting and converting operations employed in the extraction of copper, nickel, cobalt and platinum group metals.
