Mar 14, 2014 The iron itself is usually found in the form of magnetite Fe3O4, hematite Fe2O3, goethite FeO OH, limonite FeO H2O or siderite FeCO3. The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.

Goethite cm Errington Pit, Steep Rock Iron Mine Atikokan Ontario, Canada. Item number: 25221. Here is a plate of lustrous botryoidal goethite from this old iron mine .
Iron mineralisation occurs as hematitegoethite in the upper portions of the BIF, with magnetite occurring at depth below the base of oxidation which is approximately 100 m below surface. The boundary between the hematite and magnetite is interpreted to occur over a relatively narrow zone (a few metres) and as such no transitional zone was modelled. Mining Methods. Truck Shovel / Loader ...

· Flotation tests conducted on the two Iron Duke samples using oleate showed that the presence of goethite adversely affected the flotation response of the hematite but contact angle measurements showed a higher hydrophobicity for the sample containing 25% goethite. Correcting the oleate addition for the changes in surface area still showed that the goethite reduced the flotability of the hematite.

There are five major types of iron oxides found in iron ore that are economically profitable for mining: magnetite, hematite, goethite, limonite, and siderite. Iron ores, containing magnetite and hematite, are called "direct shipping ore", because they contain not less than 60% of pure iron content in them. Magnetite contains % pure ...
