FIELD: metallurgy.
SUBSTANCE: method for manufacturing agglomerates comprises the stage of heat treatment of a powder containing iron oxide having 50% of particles with a diametre of 2 mcm or less at a heating temperature of 900-1200 °C to obtain a heat-treated powder, 50% of the particles of which has a diametre of 4 mcm or more, and the stage of granulating the resulting heat-treated powder to form agglomerates. The granulation is carried out by rolling granulation. The heat treatment is carried out for a heating period of 30 minutes or more preferably when rolling a powder containing iron oxide. It is possible to use an enrichment rejects which represent a precipitate remaining after the recovery of Ni from the nickel-containing ore as a powder containing iron oxide.
EFFECT: obtaining agglomerate with high physical properties.
