Mineral deposit - Iron deposits Britannica

Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded iron formations (BIFs), so called because they are finely layered alternations of cherty silica and an iron mineral, generally hematite, magnetite, or siderite. BIFs can be divided into
