Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.. Magnetite. Magnetite is magnetic, and hence easily

ABSTRACTComprehensive utilization of tailings resources not only solves environmental problems but also creates huge economic benefits. In this paper, fine weakly magnetic particles were extracted from iron ore beneficiation tailings and silica (SiO2) was separated and purified using a superconducting high gradient magnetic separator.

The low iron-high silica manganese ores exhibited low melting temperatures; therefore, it could be used for manganese-rich slag production. The high iron-high silica manganese ore showed good reducibility with low melting temperature which makes it suitable for the production of manganese-rich slag.

Ore smelting. In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed.

Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
