Rautamateriaali
Rautamateriaali refers to raw iron ore in its natural state, before it has been smelted or processed into usable forms like pig iron or steel. This raw material is typically extracted from the earth through mining operations. The primary components of iron ore are iron-bearing minerals, most commonly iron oxides such as hematite and magnetite. These minerals are found in deposits of varying concentrations and compositions.
The extraction process usually involves open-pit or underground mining techniques, followed by crushing and screening to
Historically, iron ore has been a fundamental material for human civilization, enabling the Bronze Age to transition
