Magnetic separation of minerals using the Frantz Isodynamic Separator. General Comments: The Frantz Isodynamic Separator (FIS) separates minerals according to their magnetic susceptibility, and how the individual grains respond to the electromagnetic field versus gravity. It is a high precision, but very slow piece of equipment that is useful ...
The traditional concentration methods are magnetic separation and gravity separation. Nowadays, flotation is becoming the dominant method for kyanite beneficiation due to decreased ore grades and increased industrial demands for higher grade …
Three different types of heavy liquids and a magnetic separator (Frantz) can be found in the mineral separation room. This room is mostly used for separating heavy minerals - like zircon, monazite and apatite - from lighter minerals. Zircon and monazite are important minerals for U/Pb dating with the help of laser ablation and a mass spectrometer.
Special enrichment methods (electric and electro-magnetic separation) are used for the selective extraction of valuable minerals from bulk concentrate and mono concentrates. The end products of the processing plant are zircon concentrate, ilmenite concentrate, rutile concentrate, kyanite-sillimanite concentrate, staurolite concentrate and ...
• Kyanite recovery • Apatite upgrading • Sulphide ore recovery and separation The success of any magnetic separation process is governed by the property of the material to be collected and the structure of the separator to carry out the process. This can be expressed in the relationship between on one side the competing forces

The traditional concentration methods are gravity and magnetic separation. However, flotation is becoming the dominant concentration method due to the decreasing ore grade and the growing industrial demand for higher product grades [19,20]. Sodium oleate has been applied in the flotation of kyanite and sillimanite [21,22]. The flotation ...
