How We Can Reduce Sulfur From Iron Ore

How We Can Reduce Sulfur From Iron Ore

SULFUR. Sulfur (S) can be present as sulfides in iron ore and the coal used in the smelting process. At concentrations 300 ppm, S causes brittleness in hot iron so the iron cannot be used in steel making. Phosphorous (P) can increase the hardness and strength of steel when present between 700 and 1200 ppm, yet the presence of.

Smelting Furnace of Iron Ore Laboratory-scale experiments showed that pig irons and steels of acceptable grade can be made by arc-furnace methods from east Texas siliceous ores containing less than 25 percent iron. Under highly reducing conditions, 97 to 99 percent of the iron in the ore was recovered as pig iron. Small quantities of limestone, the minimum limited only by progressively higher.

Study On Bioleaching Of Sulfur In Iron Ore By Mixed

Pig iron is an intermediate product obtained during the smelting of iron ore using high-carbon fuel, such as coke, charcoal or anthracite. In addition to iron, pig iron consists of varying amounts of phosphorus, sulfur, manganese, silicon, and carbon. Its high carbon content makes it brittle and, hence, it is used for very limited applications.

When the temperature rose to 900 C, the sulfur content in the oxidizing roasting ore was the lowest (10.52 ), and the desulfurization rate was 71.24 . When the temperature increased from 900 C to 1000 C, the sulfur content in the oxidized roasted ore increased.
