Magnetic separation of iron ores is one of the fastest-growing segments of the minerah beneficiation industry. The tonnage of taconite ores processed annually by magnetic separation toill, in a few years, reach 100 million.

The nonmagnetic product from the LIMS is scavenged using a SLon magnetic separator to produce a magnetic product, which is further cleaned using centrifugal …

Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.

It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.

Magnetic Flocculators. Eriez Permanent Magnetic Flocculators aid in the separation of minute magnetic particles from liquids and slurries. Used widely in the iron and coal mining industries to speed settling of fine magnetic particles in ore slurries and heavy media slurries, they are finding new use in steel and other industries for agglomerating fine …

SLon magnetic separators utilise the combined force fields of magnetism, pulsating fluid and gravity to continuously beneficiate fine weakly magnetic minerals. They possess the advantages of high efficiency, low operative cost and high reliability. Until now there were about 600 SLon magnetic separators widely applied in processing oxidised iron ores, …
