Ferrous minerals are naturally occurring minerals that contain iron. They are important for various industrial applications, particularly in the production of steel. Common ferrous minerals include hematite, magnetite, and iron pyrite. These minerals are typically mined from the earth and processed to extract iron, which is a key component in construction and manufacturing. The presence of iron in ferrous minerals gives them magnetic properties, which can be useful in various technologies. Ferrous minerals are often found in sedimentary rocks and can be identified by their dark colors and metallic luster. Their extraction and processing play a crucial role in the global economy, particularly in countries with significant mining industries.
