description [...]it shows the impacts of such size difference on the concentrate regrinding stage. The product retained in each mesh was submitted to chemical analysis at the Salobo mill's chemical laboratory, where the copper content was determined by means of atomic absorption. [...]laboratory tests were conducted to simulate the rougher stage using the same feed as that used in the industrial plant. The laboratory test results point to the same trend observed in industrial scale - the rougher concentrate is significantly finer than the feed, as Table 3 illustrates. 4 CONCLUSIONS This study provided evidence that there is a significant difference between the feed and concentrate grain size distribution in the flotation process rougher stage at Salobo mill, which is similar to the situation found in a previous study at Sossego mill.
