Smelting separation behaviors and mechanisms of high-alumina rich-manganese ore obtained from metallic reduction and magnetic separation [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2019 In this paper the smelting separation of high-alumina rich-manganese ore prepared with selective reduction and magnetic separation was proposed to produce the high carbon ferromanganese alloy (HCFeMn). The rational smelting separation parameters for high-

Recovery of Pig Iron from Copper Smelting Slag by Reduction Smelting [PDF]
Archives of Metallurgy and Materials, 2018 Copper slag is a by-product obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt.% copper and 40 wt.% iron depending upon the initial ore quality and the furnace type. Main components of copper slag are iron

Slag Formation during Reduction of Iron Oxide Using Hydrogen Plasma Smelting Reduction. [PDF]
Materials (Basel), 2020 Replacing carbon by hydrogen is a huge step towards reducing CO2 emissions in the iron- and steel-making industry. The reduction of iron oxides using hydrogen plasma smelting reduction as an alternative to conventional steel-making routes has been studied at Montanuniversitaet Leoben, Austria. The aim of this work was to study the slag formation during

Conditions for Minimizing Direct Reduction in Smelting Reduction Iron Making
ISIJ International, 2018 In a 2 stage-smelting reduction process, it is favorable to lower the reduction degree of iron ore in a pre-reducing unit by lowering its temperature to avoid any troubles due to stickiness of high reduced iron ore. However, less pre-reduced iron ore can induce direct reduction in a melter-gasifier, which can increase coal ratio.
