World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
The worlds resources are dominated by lowgrade ore, though current world production of iron ore is largely by supply from deposits of highgrade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.
IOCs production process begins in the mine with drilling and blasting. The crude ore is loaded into trucks, which dump the material into the loading pockets or into the inpit crusher located in the Luce pit.
This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore. Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue unwanted materials from the iron content.
Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.
This technology eliminates the use of water in the process of concentrating the low iron content ore, which allows the tailings to be disposed of in piles as waste rock, similar to the process used in dry stacking. This process is still under industrial development.

The world will need iron ore for as long as the world needs steel. In 2020, we produced around 280 million tonnes of iron ore. Thats enough to make the steel for more than 3,300 Sydney Harbour Bridges. Were building a new iron ore mine in Western Australia. When completed, South Flank will produce highquality iron ore for around 25 years.
Brazilian iron ore miner Vale and Ningbo Zhoushan Port Group NZP have opened the Shulanghu Grinding Hub in China. Marking Vale’s first grinding hub in the country, it is located in the Shulanghu Ore Transfer Terminal, in Zhoushan City, Zhejiang. It comprises three production lines that can produce three million tonnes per annum Mtpa of ore.

2 Iron ore production. The EU has 9 member states producing iron ore, including Sweden, Norway, Austria, Slovakia and Germany. However, Sweden and Norway are the only countries in which significant quantities of iron ore are mined Fig. 1. The quantities of iron produced from the mined ore have been between 19.1 Mta and 21.8 Mta in recent years.
In 1845, the search for iron ore began in earnest, and the first major discovery was made near the present site of Negaunee. The men of the search party formed the Jackson Mining Company on July 23, 1845, and iron mining in Michigan officially began.
