As a result of the depletion high-grade manganese reserves, it has become necessary to consider exploitation low-grade ores. The main problem ore is low Mn/Fe ratio, which makes unfit for production ferroalloys. In this work, selective reduction technique was used smelting low-manganese in presence coke and fluxing material an electric submerged arc furnace obtain rich slag pig iron. product bl...
