The oxidation of chalcopyrite, CuFeS2, is still not well understood and relevant in the context of the hydrometallurgical extraction of copper Herein, we used DFT calculations within the periodic Expand Save AlertThe required pace of transition means that the availability of certain raw materials will need to be scaled up within a relatively short time scale—and, in certain cases, at volumes ten times or more than the current market size—to prevent shortages and keep newtechnology costs competitive (see sidebar “Rareearth metals”)The rawmaterials challenge: How the metals and mining sector
For example, declining ore grades result in higher energy requirements for the same amount of copper extraction (Memary et al, 2012; UNEP, 2013a), thus increasing greenhouse gas emissions In this context, tradeoffs with other problems, such as climate change and fossil energy depletion should be considered and the
