Análise de tomada de decisão na utilização de linhas de produção de cobre em uma mineradora do sudeste do Pará

Abstract

Mining is a fundamental activity for the technological and economic development, with copper production being one of the pillars of this industry due to its wide applicability in different sectors. In this context, this study focuses on Salobo mine, located in the southeast of the state of Pará, Brazil, and aims to explore productivity indicator impacts, seeking to optimize decision making in the selection process and management of grinding production lines. Using both quantitative and qualitative research elements, production data from 2023 was collected and analyzed to understand the correlation between physical availability and productivity. Furthermore, a game theory decision-based model is proposed, to optimize selection and management in production lines. The results indicate that productivity is the main factor responsible for a low performance of a production system, which has specific causes, such as operational pauses with problems related to stockpile levels, impacting the indicator performance. Therefore, this study contributes to the literature by providing insights into the management of copper production and offers practical recommendations to improve the operational performance of the Salobo mine, aiming for sustainability and competitiveness in the mining market.
