  • Hydrometallurgical procedure for the production of ferric-sulfate from fayalite slag
    Patent number: 8470569
    Abstract: The present invention corresponds to a commercial production process of ferric sulfate whose plant can be installed scaled to the requirements of the process of application of the bio-produced ferric solution based on fayalite slag generated in copper smelting plants. No previous process has established as its method of industrial application the use of these smelter slags in the bio-production of ferric sulfate solutions at concentrations above 20 g/L, including a stage of acid-slag leaching in dynamic heaps with control of generated silica and subsequent precipitation of colloidal silica and other impurities in a stirred reactor in the invented process. The ferrous solution free of colloidal silica and other impurities is subjected to a process of bio-oxidization of the clean ferrous solution by microorganisms adapted to these metallurgical solutions.
