EVALUATION OF DRY COBBING -LTV

Coarse magnetic cobbing of the crushed ore has shown the advantages of rejecting a portion of low grade ore so that the energy consumption on the down stream grinding could be reduced. With the magnetic iron recovery to the concentrate at 98%, there is an optimum size, at minus 1-inch, which achieved the rejection of 14% by weight

Iron Ore: Sedimentary Rock

Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron …

The six main steps of iron ore processing
