Abstract

Resource efficiency in a mine was assessed in this study. Two new process concepts were screened; (i) valorising metals from mine raffinate with selective precipitation with different alkalis and with possible CO2 treatment and (ii) calcium removal through precipitation from neutralising pond water for improved performance of reverse osmosis. Both new concepts were evaluated with several alkalis. Concept screening was based on computational assessment and results were verified by experiments. Experiments showed qualitative agreement with findings from computational assessment and simultaneously promoted this computer-aided methodology for rapid screening of new processes.
