Abstract

Language:

The current technological and economic constraints impose the development of efficient and eco-friendly processes for the simultaneous treatment of sulphide and oxidized ores. This work investigated the simultaneous extraction of copper and cobalt from the ternary chalcopyrite-magnetite-heterogenite system (CuFeS2-Fe3O4-Co2O3) without the addition of oxidizing and reducing reagents. The redox pair (Fe3+/Fe2+), called loop Fe3+-Fe2+, created and maintained in the reaction medium served to make this simultaneous leaching possible. The following parameters were considered: acidity (75, 204, 332 and 460 g/L), temperature an (25, 40, 60 and 80°C), and mass of iron oxide (8, 16, 24, 32 g). The copper and cobalt solubilization yields obtained were 89.93% and 95.72% at 32 g and 80 ° C. The results showed that solubilization of cobalt was not influenced by temperature.
