A method for producing a dysprosium-iron alloy for use in the manufacture of rare-earth element containing, iron-boron per- manent magnets. A particle mixture of dysprosium oxide, iron, boron and calcium is compacted, the compact is heated to form a metallic compound comprising dysprosium, boron and iron and to form calcium oxide. There is no need for additives such as cal- cium chloride that aid in particle disintegration during washing. A particle mass of -35 mesh is produced from the compact. The particle mass is washed with cold water, and the water is reacted with the calcium oxide and calcium to form calcium hydroxide, while preventing oxidation of the particle mass. The calcium hydroxide is removed from the particle mass as by repeated water washing.
