Abstract

Possibility of removal of silicon oxides and iron oxides from metallurgical slags has been found and experimentally investigated. Silicon oxide can be removed using ammonium bifluoride and is coming out of slags as ammonium hexafluorsilicate with consequent regeneration of ammonium bifluoride. Silicon oxide is regenerating from ammonium hexafluorsilicate and is a commercial product (so-called 'white soot', using widely in metallurgy as a flux). Iron oxide can be removed using ammonium chloride and is coming out of slags as iron trichloride with consequent regeneration of ammonium chloride. Slag concentrate, remaining after desiliconizing and deironing, presents lightly-opening fine-dispersed mixture of oxides of non-ferrous, rare and scattered elements.
