4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or openpit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, lowcapacity mines have rapidly disappeared.

Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces. 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.

The inclusion of medium intensity magnetic drum separation (MIMS) in combination with jigging may be considered for the beneficiation of the 61mm fraction of some friable ore bodies. The following diagram demonstrates some typical flowsheet designs for Iron Ore beneficiation of hard rock and friable ores. Innovative Plant Design
The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1xS).

For the iron ore exploration and mining industries, SGS Minerals Services provides a comprehensive range of metallurgical testwork services. Our extensive global network of laboratory and metallurgical testing facilities support most of the processes that are used in the exploration and treatment of iron ore. At the broadest level, these include:
Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel.

Iron (Fe) is an abundant and a widely distributed element in the in the crust of the earth, constituting on an average ranging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro.
Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from lowgrade deposits by surface mining.

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
The established leadzinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
Energy and Environmental Profile of the U.S. Mining Industry 22.214.171.124 Underground Mining Underground mines are established in areas with promising ore deposits. Iron ore deposits may lie deep underground. A shaft must be dug from the surface and an elevator or hoist must be installed.
