Manganese ore fines cannot be added to the submerged arc furnace directly as they will prevent even gas flow through the burden. Low gas permeability in the burden will lower the degree of pre-reduction of ore subsequently increase the carbon and energy consumption of the process. In order to utilize manganese ore fines in the furnace they are agglomerated into sinter, pellet or briquettes. In this work the melting and reduction properties Gabonese manganese sinter and Gabonese ore has been investigated in pilot scale experiments. Two experiemtns were conducted, one with 100% sinter as manganese source and one with 50/50 sinter and ore. Dolomite was used to achieve a charge basicity of 0.72 in both experiements. The composition of slag samples from the excavation of the furnace was established using EPMA(WDS), and the composotion of the tapped slag and metal was found using XRF.
