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.

Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

The metals are extracted from ore or recycled without the release of fossil gases. Iron oxide (magnetite, hematite, wustite) is converted to pure iron by the hydrogen reduction process. In traditional technology, this process takes place in coke furnaces, which results in CO₂ emissions. In the GreenIron furnaces, CO₂ emissions are zero.

The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...

In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route). The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Brown hematite ore from Amenia was used alone or mixed with other ore to produce iron. The process required about two tons of ore, limestone, and roughly 150 bushels of charcoal to produce one gross ton of iron. In 1844 the iron works and mine was purchased by Noah Gridley and his son, William, who continued the venture.
