Iron ore occurs naturally in a variety of forms from sandlike iron fines to solid rock masses. Crude ore or ore mined in the natural state seldom occurs in a pure state and requires some form of beneficiation.
Initially miners extracted the iron ore using hand tools such as pick axes and shovels but later used increasingly mechanized equipment. The ore was then shipped to Duluth via railroads which were built and operated by the mining companies.

Mining iron ore is a high volume low margin business because the value of iron is predominately lower than other base metals. As a result iron ore production is largely concentrated into the hands of a few major extractors with Australia being the largest.
Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don’t need beneficiated fines which are generated can be pelletized and used instead of being

Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small ranging from 6 to 9 kilograms.
