摘要

A process for the conversion of iron bearing residues from the non-ferrous process industry into a synthetic rock, comprising the following steps: 1 part of the wet residue is mixed with at least 0.1 parts by weight of crushed blast furnace slags and with at least 0.1 parts by weight of crushed converter slags; water is added to the mixture to obtain a stiff paste; and the paste is allowed to harden, while kept wet, to such an extent that the resulting rock is usable for construction purposes.
