Needless to say, our mining and resources industry saved us, particularly iron ore. And it continues to do so to this day. Stacks of Iron Ore. Australia is the largest producer of iron ore on the entire planet. Australia extracts 28% of the world's iron ore that is fit for profitable production.
ORES OF IRON The important ores of iron are: I. Hematite, (Fe2O3) It contains about 70% iron. Magnetite (Fe3O4) It contains about 72% iron. Siderite (FeCO3) It contains about 48% iron. Limonite () It contains about 60 % iron. Iron pyrites (FeS2) This ore occurs as pale yellow crystals and is commonly called " fools gold". It is used in the manufacture of sulphuric acid by contact process.
Magnetite ore and hematite ore are among the four types of iron ore deposits found in this area. In Minnesota, this type of iron ore is mined mainly in the Mesabi Range, one of the four ranges that make up the Iron Range of Minnesota. In Canada, Labrador is home to the majority of magnetite ore mining.
Iron Ore. Its most important mineral forms are magnetite (Fe3O4, % Fe), hematite (Fe2O3, % Fe) and siderite (FeCO3, % Fe). In Brazil, some ore that contains practically no other minerals can grade as high as 68% Fe, but the crude ore mined in Canada grades between 30 and 44% Fe.
The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state.
