Iron Ore to Sintering to Steelmaking - Analyzing Metals
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. The seven largest of these producing countries ...

Foreseeing Iron Ore Prices Using System Thinking and ...
In the iron ore's trade, demand and offer move in quite predictable cycles, leading to a possibility of previous price estimation. However, the market—supply, demand and prices—does not always behave in such a predictable way.Often, variables that have not been considered appear and act upon this 'balance' making the iron ore price shift differently than expected.

Sintering: A Step Between Mining Iron Ore and Steelmaking
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.

Understanding How The Indian Steel Industry Works | Part 1
Sintered iron ore and coke are layered inside a 100 m long furnace, then hot air at 1200 degree Celsius is blown into the blast furnace from the bottom causing the coal to burn and this heat, in turn, burns the iron ore to create molten iron at a temperature of 1500 degree Celsius. This is also called hot metal (pig iron) in the industry.
