Abstract:
The search for ways to reduce costs and increase production efficiency is visible in the current mining sector. An alternative is the application of Expert Systems capable of assisting in the plant operation in order to optimize key-results of each process, such as productivity, quality and security. Based on fuzzy logic, these systems are comprised of computer programs that control the process in the same way as a specialist of the plant. However, this type of approach requires constant monitoring and maintenance, since the benefits achieved can be lost over time. This paper aims to demonstrate a case at the Milling Plant W and C at Nexa Resources in Vazante, from the revitalization of the Expert System installed at the unit. As a result of this project, it was possible to obtain an average feed increase of 1.9% at Milling Plant W and 4.4% at Milling Plant C, as well as an average reduction in electricity consumption of 0.18 kWh/t and 0.7 kWh/t, respectively. The methodology that was applied in the project stimulated and demanded the collaboration of operators and engineers from Nexa Resources who integrally supported the project, leading to a more agile and efficient execution.
