Jernkonsentre

Jernkonsentre, meaning "iron concentrate" in Norwegian, refers to a processed form of iron ore. It is produced by crushing and grinding iron ore, then separating the iron-bearing minerals from the waste rock or gangue through various physical or magnetic processes. This concentration step significantly increases the iron content of the material, making it more efficient for subsequent use in steelmaking. The most common iron minerals found in concentrates are hematite and magnetite.

The production of jernkonsentre is a crucial step in the iron and steel industry. Raw iron ore often contains a significant amount of impurities, and concentrating it removes much of this unwanted material. This results in a higher grade of iron that requires less energy to process in blast furnaces or direct reduction plants. The resulting concentrate is typically in the form of fine particles, which are then often agglomerated into pellets or sinter for easier handling and improved performance in furnaces. Norway has historically been a significant producer of iron ore, and the term jernkonsentre reflects this industrial heritage.
