Iron is the second most common element on earth and comprises nearly 5% of the earth's crust. Iron ores are rocks and minerals that contain metallic iron that's extracted by mining. Almost of mined iron ore is used in steel production, making it …
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.
