- Iron Ore Smelting Plant
Iron is one of the most normally employed metals in smelting. Steel is produced from iron ore requiring an iron-carbon combination. Pig iron smelting was formed when the resultant iron smelting included more carbon than was required for steel production. Some typical base metals used in smelting include aluminum, bronze, silver …

Smelting reduction processes avoid this energy use because they make iron directly from iron ore and coal, omitting the need for coke ovens and sinter plants. The cyclone converter furnace consists of a cyclone for pre-reduction of the iron ore; the cyclone is mounted on a converter-type vessel in which the iron ore is then reduced to …

According to a review published by Diaz et al., oxide-type nickel ores accounted for 64% of land-based nickel ores, but more than 60% of nickel production was based on the matte smelting of sulfide ores in 1988 [].This picture has significantly changed over the past three decades because of the decrease in the reserves of high-Ni sulfide …

In SR processes, iron ore and coal are added directly to a metal-slag phase where the ore is reduced. The SR process combines the gasification of coal with the smelting reduction of iron ore. Energy consumption of smelting reduction is lower than that of blast furnace, as coking step is avoided and the need for ore preparation is reduced.

Our DRI Smelting Furnace can also be erected close to an iron ore mine site together with direct reduction plant. In such case, hot metal produced can be cast for instance to ingots or preferably granulated to suit to be used as a raw material in the day bin systems of a steel plant without a separate crushing and screening step.

Blast Furnace – Basic Oxygen Furnace (BF-BOF): This is the dominant steel production route in the iron and steel industry, involving the reduction of iron ore to pig iron in the blast furnace. BF-BOF operation relies almost entirely on coal products, emitting ~70% of CO2 in the integrated plant (BF iron making).
