Method and plant for the production of a starting material for the production of rare earth magnets

A method for the production of a powdery starting material, which is provided for the manufacture of rare earth magnets, comprising the following steps:

• providing at least one magnetic or magnetizable raw material;
• comminuting the at least one magnetic or magnetizable raw material, to create a powdery intermediate product, wherein the powdery intermediate product contains powder particles that have corners and/or edges;
• and
• chamfering the powder particles of the powdery intermediate product such that the corners and/or edges thereof are reduced or abraded to be rounded, thereby forming a powdery product, which contains chamfered powder particles;
• wherein the method further comprises:
• using the powdery product as a first starting material to manufacture first rare earth magnets;
• or
• classifying the powdery product, such that abrasion fractions created in response to the chamfering are removed and a fraction including the chamfered powder particles is used as a second starting material to manufacture second rare earth magnets;
• wherein an average particle size of the chamfered powder particles of the powdery product and the powder particles of the powdery intermediate product is between approximately 2 μm and 10 μm.
