The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
2021-12-13 · There are two main types of minerals in iron ore deposits sold in the commercial seaborne iron ore market. The first is hematite, which has high in-situ grades of high 50s to mid 60s in iron content, and is the cheapest to develop and operate at large scale, making it the mainstay of the current iron ore market. The second is magnetite.
