FIELD: metallurgy; production of ferrous metals. SUBSTANCE: pellets include iron-containing material, binder and water. Used as binder are wastes of copper board picking agents on base of ferric chloride at the following relationship of components, mass-%: iron-containing material, 73-80; pickling waste, 8-12; water, 12-15. Used as iron-containing material are dispersed wastes including oxidized and reduced iron at ratio of 3:1 to 5:1. EFFECT: enhanced efficiency of utilization of industrial wastes ; enhanced strength of pellet. 2 cl, 1 tbl |
