This article presents the results of fine manganese ore from Morro da Mina Mine/RDM concentration studies using oscillatory table in order to obtain concentrates to be used in metallurgical industries. The global, the fractions above and below 0,074 mm samples manganese contents were 28,30; 26,84 and 31,31%, respectively. It was observed that 80% of the particles in global sample were below 0,149 mm. For the optimized table concentration test, solids pulp with 15% and table inclination angle of 3º, the manganese recoveries of the global, fraction above 0,074 and below 0,074 mm samples were of 77, 81 and 62%, respectively. The manganese and impurities contents in those concentrates satisfied the chemical specifications of Morro da Mina Mine/RDM products.
