Iron Ore Pelletizing Process: An Overview

experimental shaft furnace. Commercial operation started in the 1950s in Sweden using vertical-shaft-kilns for firing the pellets. Plant capacities were between 10,000 and 60,000 tons/ year [1]. The world installed pelletizing capacity is currently estimated to be 480.7 million tons/year [2]. As shown in Figure 1 , China presents the largest production capacity, followed by the United States ...

Numerous iron ore shaft furnace models were thus proposed in the literature. The first 51 studies addressed the reduction of a single pellet by H2, CO, or H2-CO mixtures [5-10]. The 52 subsequent ones developed models that simulate the reduction zone of the shaft furnace in 1D [11-53 12]. With the aim to correctly describe the lateral gas feed ...

MIDREX® Process - Midrex Technologies, Inc.

The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H

Shaft furnace metallurgy Britannica

In iron processing: Pelletizing of firing equipment was the shaft furnace. This was followed by the grate-kiln and the traveling grate, which together account for more than 90 percent of world pellet output. In shaft furnaces the charge moves down by gravity and is heated by a counterflow of hot combustion gases, but the Read More

Leading the way to decarbonisation - LKAB

In the 1960’s, LKAB’s production, like the rest of the iron ore industry, was based on sinter with a shaft furnace that accounted for 192kg C02 emission per tonne. LKAB has since invested enormously in optimization of its processes and energy efficiency in order to bring its emissions to 31kg CO2 per tonne in 2013. Unfortunately, the rest of the industry has not yet made these ...
