Estimating global copper demand until 2100 with

2018-5-1  To derive model parameters for the top-down regression analysis, we used time series of global copper production (as a proxy for demand), population and GDP/capita for the period 1950–2010. The result is shown in Fig. 1. We found a correlation with a high R 2 of 0.991, indicating the regression fits the time series of global copper production
