magnetite iron ore smelting pdf

titaniferous magnetite smelting practices and also improve overall metal recovery efciencies. Unlock-ing the full potential of this complex ore is of economic interest, especially in China and South Africa, as both regions have large endowments of titaniferous magnetite and a history of processing these deposits for iron and vanadium.

Natural Resources Sustainability Iron Ore

Natural Resources Sustainability Iron Ore

When the iron grade is too low to transport the ore, the ore must be agglomerated which demands a considerable amount of energy 1,500 MJton of ore during pelletisation 8. Because the energy demand depends on the iron grade, a magnetite with an iron content of 72 can be compared to a hematite with an iron content of 62.

Ore Size Does Affect Direct Reduction Of Titaniferous

Ore Size Does Affect Direct Reduction Of Titaniferous

magnetite which also contains a substantial amount of vanadium is pre-reduced in a rotary kiln, using coal as reductant. The residence time in the furnace is some six hours, and about 50 metalliation of the iron is achieved in the kiln. Pre-reduction serves to decrease the energy requirement during subsequent electric smelting of the charge.
