Australia’s Iron Ore Product QualityImpurities The Bauxite Index

Australia’s iron ore production has seen strong growth over the past five decades and over blended with the premium Brockman ores to manage iron phosphate silica and alumina historical production data were then retrieved for all active iron ore mines sinceThe rule of thumb is that on a weight basis any mass of silica that reacts in the refining process will cause an equal loss of caustic soda and an equal loss of alumina

Iron ore WikipediaDifferent Types of Iron Ore Mineral Processing Metallurgy

Iron ore is the raw material used to make pig iron which is one of the main raw materials to make steel—98 of the mined iron ore is used to make steel Indeed it has been argued that iron ore is more integral to the global economy than any other commodity except perhaps oil Iron formation consists of iron ore such as siderite magnetite and hematite with silica in the form of chert jasper etc generally in bands but sometimes not distinctly so The bands of iron ore are at times high grade but are often mixed with a good deal of silica the whole making an ore too lean for use without concentration
