GB2261225A Air separation, iron ore reduction and power

Air is compressed in a compressor 32 and a first stream of the compressed air is separated in a plant 34 into oxygen and nitogren. A stream of the oxygen is reacted in a gasifier 22 with coal to form a reducing gas. The reducing gas is reacted with iron ore in a shaft furnace 24 to form molten iron and a residual fuel gas. The residual fuel gas is compressed in a compressor 40 and is combusted

Feb 19, 2021 The presence of sulfur in iron concentrate affects the price of iron ore concentrate because sulfur in steel decreases its quality. Furthermore, sulfur in iron concentrates causes environmental problems, especially sulfur dioxide emissions during the smelting or pelletizing processes. So, the separation of S from iron (Fe) is important.

The blue and grey water footprint of construction

Jun 01, 2018 Fig. 1 shows the six steps of the steel production chain: (1) mining of raw materials; (2) processing of raw materials (beneficiation, calcination and coking); (3) iron ore reduction; (4) air separation; (5) ferroalloy production and (5) steel production. Every step needs the input of energy (red arrows) and water (blue arrows) and results in

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
