Iron ore BHP

The world will need iron ore for as long as the world needs steel. In 2020, we produced around 280 million tonnes of iron ore. That's enough to make the steel for more than 3,300 Sydney Harbour Bridges. We're building a new iron ore mine in Western Australia. When completed, South Flank will produce high-quality iron ore for around 25 years.

Environmental impact of iron ore mining Wikipedia

Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is

Further processing involves the agglomeration and thermal treatment of the concentrate to produce pellets that can be used directly in blast furnaces, or in direct reduction steel-making plants. The pellets contain 65% to 70% iron, which is a higher iron grade than the hematite DSO currently being exported from the Hamersley region

Mineral processing Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
