Thus, the feed to the rougher bank is a blend of the fresh and CST feeds. The grades of the rougher and CST feeds are 0.24 and 0.32 %Cu, respectively, while the volumetric and mass flow rates of the CST feed are 22 and 11.6 %, respectively. One can then back-calculate the grade of the freshly mined copper ore to be 0.23 %Cu from mass balance.
