oai:localhost:PNK-77502023-04-11T03:07:17Z Can ultimate recoverable resources (URRs) be assessed? Does analyzing declining ore grades help? Friedrich-W., Wellmer Roland W., Scholz Dennis, Bastian URRs analyzing declining CC BY Inspired by a paper by Teseletso and Adachi (Miner Econ 8(10):21, 2021), the hypothesis regarding the declining grade of mined copper ore and its possible use as a guide to the future of ultimate recoverable resources (URRs) is tested. As a time axis, cumulative production is taken. Grades can be either grade of cumulative tonnage or annual production grade. Correlation can be linear (grade and tonnage) or semi-logarithmic (grade linear, tonnage logarithmic). We first show that the assumption that the highest correlation is the best guide to the future may be a fallacy. This is the linear correlation between grades of cumulative tonnage and cumulative tonnages since 1959, i.e., 85% of all copper mined historically with a near-perfect correlation approaching one (R2 = 0.97). This leads to implausibly low results of the URR, clearly demonstrating that this trend must shift in the future. 2023-04-11T03:07:17Z 2023-04-11T03:07:17Z 2023 Book https://link.springer.com/article/10.1007/s13563-023-00368-0 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7750 en application/pdf Springer |
