Abstract
Screening plays a crucial role in the beneficiation process. This study investigated the replacement of a vibrating screen in the secondary crushing circuit at the Salobo mine, aiming to optimize particle size distribution and operational efficiency. Samples were collected before and after replacing the 75×150 mm screen with a 75×75 mm screen, analyzing the granulometry and its impact on the crushing process. The results indicated an increase in the amount of material passing through the 50 mm screen, a reduction in the maximum particle size, and a higher crushing rate, accompanied by an increase in electrical consumption. The modification improved circuit efficiency, contributing to the overall plant performance and highlighting the importance of classification screen control in mineral processing.
