Processing 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...
متن کاملRECOVERY OF IRON FROM LOW-GRADE HEMATITE ORE USING COAL-BASED DIRECT REDUCTION FOLLOWED BY MAGNETIC SEPARATION
In the present work, iron recovery from a low-grade hematite ore (containing less than 40% iron), which is not applicable in common methods of ironmaking, was studied. Non-coking coal was used as reducing agent. Reduction experiments were performed under various coal to hematite ratios and temperatures. Reduction degree was calculated using the gravimetric method. Reduced samples were subjected...
متن کاملCharacterization of Sangan low-grade iron ore and its processing by dry low-intensity magnetic separation
In Sangan iron mine nearly two million tons of low-grade iron ore has been extracted and deposited in the mining site and currently no action is made on them. On the other hand, the mining site is located in the semi-arid region and wet processing has been restricted due to water shortage. In this research, the upgradation of Sangan low-grade iron ore from mine B has been performed by dry low-i...
