was assumed that dissolution of manganese ore in our case with P. citrinum also followed indirect reaction mechanism. During the bioleaching process, manganese may precipitate. Also, manganese ions adsorbs on the surface of the MnO2 ore particles at pH>5 (Marshall, 1979) which may limit further leaching (Buys et al., 1986).
found in New Zealand. Worldwide, these deposits are mainly silie ores, with less common carbonate ores, and rare, oxides ores. Manganese Alloy The production of manganese alloy from manganese ore is an energy intensive process and therefore, apart from manganese ore, power plays an important role in the production of ese alloy.

The disadvantages of these methods are the need for a process of hightemperature reduction roast, low degree through extraction of manganese, concentrated flow is rgence of manganese ores with a solution of sulfuric acid at a current of sulphurous anhydride or a mixture of sulphuric and sulphurous acids (4,5).
Problem 95 Hard Difficulty. Manganese is derived from pyrolusite ore, an impure manganese dioxide. In the procedure used to analyze a pyrolusite ore for its mat{MnO}_{2} content, a mat{g} sample is treated with mat{g} oxalic acid left(mat{H}_{2} mat{C}_{2} mat{O}_{4} cdot 2 mat{H}_{2} mat{O}right) in an acidic medium.

medium ores are converted completely to MnO at 1100˚C. However, the ore with low manganese content was converted to MnO and Mn3O4. Consequently, it is clear from the results that Mn ores with high and medium MnO2 content are more reactive than those with low MnO2. Therefore, high MnO2 content Mn ores are preferable to get good eco

The present work examines the reduction rate of MnO by solid carbon from two different charges during the ferromanganese production process. Charge composition and temperature were used as experimental variables in this investigation. The emphasis was on how different charge compositions affect the reduction rate of MnO in the temperature range of 1400 to 1500°C.
