Magnetic Separation - Washington University in St. Louis

The device used to separate minerals based on their magnetic properties is called a Frantz Isodynamic Magnetic Separator. The magnetic separator consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near its exit end. Varying the strength of the magnetic field and/or slope of the separation trough is used to separate minerals. All forms of mineral separation

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.
