Using Technoeconomic Modelling to make Investment Decisions

Speaker: Dr Grant Ballantyne, Director Technical Solutions, Ausenco

Abstract:  The goal of mining is to increase metal production while simultaneously reducing operating expenses and inventory.  However, siloed thinking typically reduces the goal to increasing throughput, increasing recovery or reducing energy.  This presentation will highlight case studies where we have used technoeconomic modelling to show the benefit of new technologies such as bulk ore sorting and coarse particle flotation to achieve the real goal of mining.
