Glacialle Tiu
ESR4
Project Overview
This project aims to improve the geometallurgical model for a complex ore type, in this instance a poly-metallic base metal ore with additional precious and penalty elements. These types of ores pose particularly tough challenges for successful production forecast because of the mixed Zn-Pb-Cu base metals, the complex association of the beneficial Ag and Au, and the presence of influential elements such as As, Sb, Mn, Mg and Hg.
The project will deploy a number of analytical tools including reflected light petrography, SEM-EDX and LA-ICP-MS as well as modelling to predict the behaviour of the ore through an improved mineral processing plant.
