The ore is first ground into fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt. Froth Flotation Method: This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in the water.
Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 % of the total global iron ore …
Blast furnaces are a common part of large industrial steelmaking plants, which also include coke ovens, sintering beds, and other areas for ore dressing. Iron is extracted from its ore using carbon in the form of coke. An iron-containing ore is combined with coke and limestone to form what is known as the charge.
