Abstract
Disclosed herein is a high gradient magnetic separation (HGMS) apparatus, in which ferromagnetic metal wool is used to separate, for example, iron powders from water. Due to the high magnetic gradient around the metal wool, the separation of the iron powders takes place. Because of an improvement of the metal wool used in this HGMS apparatus, iron powders and the like can be collected at a high collecting efficiency, and the renewal operation of the metal wool can be performed in a short period of time. The improvement according to the invention resides in employing an amorphous metal alloy for the metal wool.
