  • Advances in microbial leaching processes for nickel

    2015-7-21 · Generally, higher grade lateritic minerals are processed industri-ally through pyro- and hydrometallurgical routes. In pyro-metal-lurgical method, the ores are subjected to process through certainenergy-consuming processes like drying, calcination, roasting, reduc-tion, and smelting, and in case of hydrometallurgical methods,acids and solvents are used for treatment of ores to leach out ofmetals. Industrially, the nickel extractions from the lateritic miner-als are also done by a process called as “Caron process,” in whichthe both pyro and hydrometallurgical procedures are followed fornickel extractions from lateritic minerals. These metallurgical pro-cesses are economically viable and industrially acceptable, when theextraction of nickel is done from the relatively higher grade later-itic minerals. However, the majority of lateritic minerals availablein the globe are poor in nickel content, hence the existing pyro andhydrometallurgical procedures (PDF) Green chemistry in mineral processing: Chemical and,Green chemistry in mineral processing: Chemical and physical methods to enhance the leaching of silver and the efficiency in cyanide consumption The leaching process is found to occur in two
