In 2014 we mined 63.9 million tonnes of iron ore and 7 million tonnes of coking coal, overall we produced 93.1 million tonnes of crude steel. Processing To manufacture steel, it is first necessary to produce pig iron. This is produced from iron ore by beneficiation with carbon. The carbon is .
The iron ore shown to the right was excavated from Skgar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.
Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces. Pig iron is supplied in a variety of ingot sizes and weights, ranging from 3 kg up to more than 50 kg. The vast majority of pig iron is produced and consumed within integrated steel mill complexes.
History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
Modern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an iron-rich clinker called sinter. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.
Vale is the worlds biggest producer of iron ore and pellets, raw materials essential to the manufacture of steel. Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel companies.

EXTRACTION OF IRON ORE. Occurrence: Iron does not occur in the native state as it is oxidized easily. Iron in elemental state occurs in meteorites. Iron is an important constituent of hemoglobin of blood. Iron is also present in plant and animal tissues. The most important ores of the iron ore are the oxides, carbonates and sulphides listed below.
New Zealand had limited deposits of iron ore, but the deposits of ironsand were massive. It had been used by some early settlers to manufacture steel and pig iron, but the material could not be smelted in common bloomeries or blast furnaces. A few smelting companies formed in the late 19th and early 20th centuries, but were unable to process .
