Mining iron ore typically involves finding a fertile site, drilling and blasting the ore, and then transporting it to the primary crusher for processing. Crushed ore is sorted over screens and resized to different specifications (lump and refined products). After the processing, a stacker builds a stockpile in the stockyards.

Process Processing of the ore ranges from simple crushing and screening to a standard size, through to processes that beneficiate or upgrade the quality of the iron ore products. This is done by physical processes, which remove impurities by differences in particle density or size gravity or size separation. Processing may be wet or dry.

"It's difficult for us to influence what goes on there and the energy used is significantly higher in the smelting process than it is in the mining process." The main source of carbon emissions comes from the use of metallurgical coal as fuel or coke to melt the waste material - also known as gangue - from the ore to extract the iron.

Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock.

An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing).
