Fungal Leaching of Manganese Ore
Bioleaching is technologically feasible for extraction of manganese from low grade ores (containing manganese less than 35% by weight). The principle involves the non-enzymatic reduction of pyrolusite [Mn(IV) oxides] to +2 oxidation state by fungi with the production of metabolites such as oxalic acid and citric acid. In the present investigation, a fungal strain, Penicillium citrinum was isola...
متن کاملThe Smelting of Manganese Carbonate Ore
The practice of manganese ferroalloy smelting has traditionally been based on utilising oxide ores which typically contain a high level of manganese. This preference for oxides has even been extended to the modification of natural carbonates into nodulized oxides. However smelting practices developed over the past 30 years have created a market for natural manganese carbonate ores, driven in pa...
متن کاملProcessing of Low Grade Fine Manganese Ore Using Flotation Method
Application of gravity and magnetic separation methods to upgrade low grade Manganese ores from Venaj Mine has been reported elsewhere. This paper discusses the results of flotation tests, as well as combination of flotation and magnetic method to concentrate fine particles (less than 150 microns) of manganese ore. Results obtained from various direct and reverse flotation tests, using differen...

متن کاملBioleaching of Low Grade Manganese Ore with Penicillium citrinum
A native microorganism, Penicillium citrinum was isolated from the top soil of a manganese mine. Based on its efficiency for manganese solubilisation, it was utilized for the leaching of a low-grade manganese ore. The effects of various parameters such as pulp density, particle size, sucrose concentration, inoculum size and bioleaching duration on manganese ore were studied. The optimised condi...
