Processing of Magnetite Iron Ores - Comparing Grinding ...

There is a rich and long history of magnetite ore processing in Western countries, including large operations such as Cleveland Cliffs in the USA and LKAB in Sweden, as well as smaller operations like Savage River in Tasmania. The challenge for virtually all magnetite operations is to minimise operating costs, which is dominated by the cost of power required to fine grind the ore in order to ...

The stirred mill was more beneficial for grinding complex ores and improved the degree of liberation of sphalerite in the complex Pb–Zn ore. In our previous work, we have found that the iron grade and recovery of fine-grained magnetite can be improved by regrinding with the stirred mill (Zhang et al., 2008, Zhang et al., 2010, Xiao et ...

Processing - Citic Pacific Mining

As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it’s screened and fed into the ball mills. The ball mills are also the largest of their type – they have an internal volume of around 650 cubic metres and inside them are 800 tonnes of steel ...

Mineral processing - Wikipedia

The force experienced in the magnetic field is given by the equation f=m/k.H.dh/dx. with k=magnetic susceptibility, H-magnetic field strength, and dh/dx being the magnetic field gradient. As seen in this equation, the separation can be driven in two ways, either through a gradient in a magnetic field or the strength of a magnetic field. The different driving forces are used in the different ...

Magnetite Applications and Uses African Pegmatite

Magnetite is the most common ore of iron; it is attracted to magnets and can itself be magnetised. It is used primarily in the production of iron and steel. It is used in the Haber-Bosch and Fischer-Tropsch processes as a catalyst, for the production of ammonia and hydrocarbons respectively; and as a tool in the degradation of contaminants from industrial processes.

Iron Ore - Mining Artifacts

The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 3-7% silica and less than 3% aluminum. The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be reduced to enable efficient magnetic separation to provide a high purity magnetite concentrate. This determines the energy inputs required to ...
