HGMS cyclic
The Metso High Gradient Magnetic
Separators (HGMS) are used in many
magnetic separation applications.
Among these are the processing of more
strongly magnetic minerals of Fe, Co
and Ni as well as less magnetic minerals
such as rare earths and industrial minerals, which normally are not regarded as
treatable by magnetic processes. Even
weakly, para-magnetic materials can
be processed by the HGMS including
brightening of kaolin clays, separation of
galena, chalcopyrite and sphalerite; removing Fe and Cr from glass sand; and
cleaning of refractory materials, coal
and phosphate concentrates.
Application
The capacity of the Metso HGMS varies with
application and the parameters for selection of
a suitable HGMS unit for a specific process is
normally established by proper testing of the
material in a laboratory unit.
The operating parameters sought are matrix
loading, superficial pulp flow velocity, magnetic
strength and matrix grade. The test data are
then used to select the canister diameter and to
determine the cycle time.

Operating principle
© Metso Corporation, TS HGMS cyclic 1105-en
Sometimes the sizing process reveals that a
cyclic machine may not be a practical or economical selection.
This is typical when the magnetic product is
around five percent of the feed tonnage.
On such occasions a continuous machine may
prove to be a more suitable selection.
Advantages
•t Broad range of applications
• tWide range of equipment sizes and capabilities
