Figure 7. Route-specific sensitivity heat maps for the Ausmelt case (A) and the double-flash case (B). Parameter sets reflect the inventory structure of each route and are not intended for direct parameter-by-parameter comparison. Steel-ball and explosive inputs in panel (A) are disaggregated upstream inputs for domestic-concentrate mining and beneficiation, whereas analogous inputs are embedded in the imported-concentrate background process for the double-flash case. Values show absolute changes in the economically allocated cathode-copper footprint under one-at-a-time ±10% input changes. Imported-concentrate sensitivity is calculated from the grade-converted production contribution after economic allocation, not directly from the factor displayed in Figure 6C.
