The broker forecasts China's demand for iron ore to peak at 1.28bn tonnes in 2018 and then gradually decline to 1.1bn by 2023 because of falling crude steel production and increasing use of scrap. Domestic supply from China is expected to decline to 40mt by 2023 but remain at around 16% of China's total iron ore demand.
With low iron content degree (Fe < 56%), Fe content degree improvement process is required for this iron ore waste to be able to use as feed material in smelting process into pig iron. Pig iron is a solid form of hot metal, obtained from iron ore or scrap recycling, and it is processed with blast furnace or electric arc furnace.
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. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
As the world's leading steel and mining company, our business operations extend from the mining of iron ore and coal to the production of the full range of steel products and services. In 2016, we produced 55.2 million tonnes of iron ore and 6.9 million tonnes of coking coal, a form of carbonised coal burned in blast furnaces to melt iron.

Brazil had increasing trend in iron ore production in the study period whilst its steel production growth was marginal. Its iron ore production rose from 2.9 Mt in 1950 to 322 Mt in 2005, in contrast its steel production grew from 0.79 to 31.61 Mt (Fig. 7a).
Pig Iron is actually produced in Blast Furnace. Principle raw materials are: Iron Ore, Coke and Lime Stone. As iron ore contains a lot of oxygen, carbon in form of coke is used for direct reduction of iron ore.
Industrial iron production starts with iron ores, principally hematite, which has a nominal formula Fe 2 O 3, and magnetite, with the formula Fe 3 O 4. These ores are reduced to the metal in a carbothermic reaction, i.e. by treatment with carbon. The conversion is typically conducted in a blast furnace at temperatures of about 2000 °C.
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.
