Copper Tailings Reprocessing

  • Common Copper Tailings Reprocessing Methods

    2020-11-16 · In the reprocessing course of copper tailings, the vulcanization flotation can be used to acquire high-grade copper concentrates. It has a good recovering result. However, the vulcanization flotation has high technical requirements and a large investment. It is suitable for large scale copper tailings processing plant.Economic Potential for reprocessing Copper Mine Tailings,2016-7-31 · Four copper mine tailings in Chile were investigated for their elemental and mineral composition, in order to evaluate the potential for economic reprocessing. The sample material, taken for processing had Cu-contents between 0.1 and 0.5 %. Copper was abundant in various primary (mostly chalcopyrite) and secondary (cuprite, atacamite, brochantite and chrysocolla) minerals. This report includes tests of laboratory size. Chemical sulfuric acid leaching was assessed in comparison to bioleaching. Copper bioleaching resulted in recoveries between 20 % and 70 %. For chemical leaching the recovery was 4 % to over 80 %. The recovery was strongly dependent on the mineralogical composition of the copper minerals. Secondary copper minerals were very scarcely abundant in the solid leaching residues. Using chemical leaching a very low copper recovery for one sample could be explained by the presence of the recalcitrant mineral chalcopyrite as the almost unique copper bearing mineral. In contrast, a significant copper

    2019-9-13 · The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today’s price, US$5,842/tonne, if that material could be reprocessed and an extra 2.5% of copper recovered (or more), then that’s an additional US$162 million+ of revenue.
