Integrating Pre-Concentration Technologies to Maximise Resource and Eco-Efficiency

Abstract

Mining and processing of larger volumes of material per tonne of product will inevitably be required to deal with declining ore grades. This paper includes case studies that apply the methodology developed by the authors over the years that evaluates the pre-concentration options including assessment of ore heterogeneity using geostatistics, mathematical process modelling, preliminary layouts, cost estimates and financial implications for the overall operation (mine, pre-concentration and downstream processing).
