ABSTRACT:
In the manufacture of cold-moulded briquettes from iron-containing waste metallurgical material mixed with a binder, in order to obtain high-strength briquettes and almost complete reducibility, magnetite waste metallurgical material such as scale (1) is mixed with haematite fine material (5) to form a layer (10) of haematite line materials (5) enveloping the individual magnetite particles (9), after which the binder is added to the mixture (FIG. 1).
