Every production metallurgist will inevitably face metallurgical accounting in their career. It is a vital process to ensure accurate tracking of production through the mine value chain. Despite this, it is commonly perceived as ‘bean counting’ and relegated to junior members of the metallurgy team, often using a complex web of spreadsheets with minimal documentation. In recent years, metallurgical accounting has received more attention which has caused many sites to request audits against the recommendations outlined by AMIRA P754 Principles of Metal Accounting (Code 1.2 Release 1.3). Typically, sites want the auditing efforts to focus on their software systems, believing that they are the largest source of error in the metallurgical accounting process. While many are keen to highlight the flaws and non-compliance of spreadsheet-based systems, this distracts from the actual issues found to be plaguing accuracy and precision. In this paper, case studies are used to highlight examples of where the main metallurgical accounting errors observed during audits conducted by JKTech were found to be; weightometer-derived mass flow rates, in-plant samplers and mass balancing techniques. Addressing these areas are essential for improving accuracy of production reporting and therefore decision-making.
