An Overview of Manganese Recovery by Hydro and Pyro-Metallurgical Routes

This review comprises of information about the recovery of manganese through leaching and carbothermic reduction routes. In industrial processes, various critical parameters such as ore size, temperature, pressure, gas atmosphere and ore composition etc. affect the reduction or recovery of Mn from ores. Authors have tried to bring those critical parameters in this review which is currently being considered as important industrial parameters for Mn ore processing. This paper deals with both pyro-metallurgical and hydro-metallurgical routes for Mn ore reduction and gives brief summary about the critical parameters.
