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...

This study investigated the optimum conditions for the leaching of manganese-rich iron ore for subsequent beneficiation studies in laboratory scale. The experiments were carried out by varying the concentration of H2 SO4 solution and the leaching temperature. The properties of the iron ore was characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM)...

when Couper of Glasgow observed the first cases among five manganese ore crushers. He described a series of nervous phenomena: muscular weakness, paraplegia, tremor of the extremities, a tendency to lean forward while walking, whispering speech, and salivation. Since then a number of writers have made further observations and recognized manganese as a poison affecting the central nervous system...

The processing of mining products in indonesia has not been utilized optimally. One them is manganese ore. Way kanan one indonesia's potential ore sites. leaching study used a -200 mesh way that was reacted with sulfuric acid at concentrations 0.1 M, 0.5 and 1 as well corncob reductant. To separate the dissolved iron process, sulfate solution purified sodium hydroxide then filtered to have free...
