    Environmental impact of iron ore mining

    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).Magne- tite concentrates are relatively easy to pelletize : the particles are granular (rather than plate-like) in shape, with a high surface area, and with a surface uncontami- nated by flotation agents; if properly treated they will oxidize during firing, giving a useful heat release.Read more

    Magnetie Iron Ore

    Magnetite ore is suitable for processing into iron ore pellets for use in modern steel production and currently accounts for approximately 50% of global iron ore production. While magnetite is generally a lower-grade deposit, it is globally accepted as a viable andand oxidation. The recoverable iron mineral is finely dis-seminated magnetite and the ore must be ground to about 80% —325 mesh for liberation, the concentrate containing about 65% iron and 8% silica. By 1945 research and development at the Station hadRead more

Drop number and compressive strength tests for green and dry pellets; porosity, compressive strength and reducibility tests for fired pellets were carried out to determine the influence of mixing ratios of both iron oxides on those pellet properties. · The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing …Read more
