Sphalerite is a sulfide zinc mineral, which also contains supporting metals such as iron, copper and lead. In this work, we dealt with the extraction of iron from sphalerite in a new oxidation system. Manganese dioxide was used as the primary oxidant, and KI was used as a secondary oxidizing agent with the aim of creating an I2/I- oxidation cycle in a sulfuric acid medium. The thoughtful characterization (X-ray diffraction - XRD, Scanning Electron Microscopy - SEM, Energy-dispersive X-ray spectroscopy - EDS) of the initial sample, as well as the precipitate formed after leaching was done. During the leaching tests, process parameters were varied.
