2021-12-11 · This iron can also be used in steel production or purified further to give wrought iron. Waste gas mixture that exudes from the furnace contains majorly nitrogen, 30% carbon(II)oxide and about 10% carbon(IV)oxide. These waste gas mixture is used in pre-heating the air blast and the iron ore at the initial stages of the extraction process.

Iron Ore - an overview | ScienceDirect Topics
Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.

Waste rock can be processed to a desired gradation by crushing and sizing, like any other source of aggregate. The hardness of the waste rock is determined by the rock type. For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense.

Waste and landfill - LKAB
The majority of our operational waste consists of rock types that are not ore, known as waste rock, which is separated from the iron ore and dumped in landfill. Waste rock is also used for construction purposes and to fill in mined ore bodies. Operational waste also consists of wet waste or tailings that is deposited in a tailings dam.
