Iron Mining Process
Separation The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate. Pellets The concentrate (the wet taconite powder) is rolled with clay inside large rotating cylinders.

Conversion of Chromium Ore Processing Residue to Chrome Steel
The reduction of iron oxide at the interface of molten slag and solid carbon disk resulted in the CO gas formation. The CO bubbles acted as a barrier for the direct contact between iron oxide and carbon. They found that the reduction rate increased as they evacuated CO, allowing the direct contact between iron oxide and solid carbon.

Sunflag Steel | 5 Steps of Steel Manufacturing
The first step to making steel is to make the iron from which it will be made. This is usually done with the help of coal. Raw bits of iron ore, coke, and lime are put into something called a blast furnace. Here, they result in molten iron (which is also called " hot metal Steelmaking Steelmaking is of two types – primary, and secondary.

How we make steel | British Steel
Coke, iron ore, sinter and limestone are fed – or charged – into the top of the furnaces. A hot air blast of temperatures around 1,000°C is injected at the bottom of the furnace through nozzles called tuyeres. As the coke burns, temperatures higher than 2,000°C are reached and this heat creates molten metal (iron).

iron processing
Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
