Pdf value addition and beneficiation of iron ore

Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes

    Dec 01, 2010 Iron ore slime which is a waste material contains 56% of iron. Two different chemical treatment methods and electrowinning method were separately studied to upgrade iron content up to 60% or above. Acid extraction and alkali extraction can upgrade iron content maximum 63% (w/w) and 65 % (w/w) respectively. Electrowinning directly produces high purity iron without involvement of blast
