Magnetic Separation Mining Fundamentals. The most commonly used magnetic separator is the Frantz Isodynamic Magnetic Separator. It consists of a large electromagnet, through which mineral mixtures are passed on a metal trough. By varying the strength of the magnetic field or the slope of the tough, different minerals can be separated.

At 1.8 amperes, the magnetic field strength in the narrowest part of the gap is approximately 20 kilogauss. How the L-1 Isodynamic Laboratory Separator Works Material is fed into one end of the magnetic field of an electromagnet having two long pole pieces shaped to a special contour (with a long narrow air gap between them).

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

Principles of design. The Isodynamic ® Separator consists essentially of an electromagnet having two long pole pieces shaped to a special contour (shown in simplified form in the sketch below) with a long narrow air gap between them. Materials to be separated are fed into one end of the magnetic field (1) and travel through its entire length.

Mar 01, 1992 In any non-uniform magnetic field, including the isodynamic, such particles experience different forces in different parts of the magnetic field of the separators. This dynamic inconsistency breaks the selection of the desired mineral fragments, and leads to losses in the accuracy of separation.

Frantz’s standard proprietary grids are effective for most applications, exemplifying a principle revealed early by Mr. Frantz: For effective magnetic separation, the size of the collecting edge should be on the same order of magnitude as the size of the particles to be captured.
