The study showed that under optimal conditions of 9.7 M HCl and 0.4 M extractant concentration, the iron extraction rate was 97.19%. In addition, it is worth noting that the iron extraction process is endothermic, so specific temperature requirements must be met during extraction. Furthermore, the fact that other metal ions were not extracted ...

Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.

As societies progressed, humans began to extract iron from terrestrial sources, marking the transition from the use of meteoric iron to smelting iron ore. One of the earliest known methods of iron smelting was the bloomery process. This ancient technique, dating as far back as 1200 BCE, involved heating iron ore in a furnace with charcoal.

Iron is extracted from its ore, haematite, by reduction with carbon. This takes place in a blast furnace (named after blasts of air [20% oxygen], heated to 1000 °C, which are blasted into the bottom of the furnace): A mixture of crushed iron ore, coke (an almost pure form of carbon) and limestone is fed into the top of the blast furnace.
