Magnetite has simple mineral composition and can be acquired iron ore concentrate with high grade and high recovery through using single low intensity magnetic separation method. If ore contains large amount of wall rock and will appear numerous single gangue when crush into coarse granularity and can use magnetic pulley for discarding tailings
Ore, which contains an economical use of iron, is called an iron ore. There are many types of iron ore, magnetite (Fe3O4), hematite (Fe2O3) and (FeCO3), etc, which are mainly used for iron making. Iron ore is an important raw material for iron and steel production enterprises. Flotation beneficiation separate ore at three physical statuses
Magnetite ore and hematite ore are among the four types of iron ore deposits found in this area. In Minnesota, this type of iron ore is mined mainly in the Mesabi Range, one of the four ranges
The geochemical analysis also showed that the deposit contained a very good metal grade iron ore with an average composition of 2.55 PPM of magnetite and also an average composition of 1.6PPM.
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 separated from the gangue minerals and
