Course description

A metal accounting system is the key tool for determining the real performances of a metallurgical installation and achieving Operational Excellence. Such a system can cover the full production process from the mine to the final smelter and/or refinery. Essential to manage base metals, it is crucial when processing precious and critical materials. This short course is an introduction to the main principles and interests of a metallurgical accounting system. A review of the best practice recommended by the AMIRA P754 code for metallurgical accounting is first presented. It is then demonstrated that before implementing a dedicated software, several key subjects must be properly addressed such as high-quality sampling and accurate measurements, adapted stock management, selection of the appropriate flowsheet or rigorous data storage. Once those key features will be properly implemented, a data reconciliation algorithm will be the “icing on the cake” that will finally improve the accuracy of the overall metal balance, allowing to get consistent data for the main KPIs calculation.

At the end of the course, a demonstration of the INVENTEO metal accounting solution will be provided.
