摘要：

Recovery of manganese from electric arc furnace dust (EAFD) of a ferromanganese production unit was investigated using reductive leaching in sulfuric acid (H2SO4). Three different reducing reagents, oxalic acid, hydrogen peroxide and glucose, were tested. Effect of different leaching parameters on the leaching and separation selectivity of manganese from iron was investigated. Iron concentration in solution was also determined, since iron was the major contaminant in the leach liquor. From the results complete leaching of manganese was achieved at 0.31 mol/L oxalic acid concentration, 2 mol/L H2SO4, a liquid/solid ratio of 30/1 at 70 degrees C and with 90 min leaching time.
