Reprocessing of tailing from Erdenet copper ores: Optimization of the chemical reagents for the leaching

Abstract

This thesis paper is conducted as an extension of the "Adriana" project, focusing on the exploration of reprocessing possibilities for the tailings generated by the Erdenet copper and molybdenum mining company. The main objective of this study is to investigate the feasibility of employing the mechanical flotation process to recover valuable minerals fromthe tailings. The decision to undertake this research is motivated by historical data obtained from EMC LLC, which indicates that the copper content in the tailings exceeded 0.1% as a result of past operational activities and the absence of advanced technological approaches. This finding highlights the potential value and significance of implementing an efficient reprocessing strategy to extract valuable resources from the tailings, thereby mitigating waste and enhancing resource utilization in the mining industry.
