Iron Mining Process

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.

Mines and environmental impact

Problems with mining waste. Mining waste has different characteristics depending on the type of ore being mined. Our Swedish ores can be roughly divided into oxidic and sulphidic ores. The oxidic ores predominate in Norrbotten's iron ore field, while the sulphidic ores are more prominent in, e.g. the Skellefte field in Vsterbotten.

What is the byproduct of iron ore?

Feb 05, 2018The main inputs are iron ore, coal, limestone and recycled (scrap) steel. The main ore-based production routes are: ironmaking via the blast furnace (BF) followed by steelmaking in the basic oxygen furnace (BOF), and ironmaking via direct reduction (DRI) followed by steelmaking in the electric arc furnace (EAF).
