PROCESS FOR REDUCING THE IRON CONTENT OF CAO-RICH SLAGS FORMED DURING THE DESULPHURISATION OF CRUDE IRON

摘要

A process is described and claimed for reducing the iron content of a CaO-rich slag which is formed during the desulphurization of molten crude iron which comprises adding finely-ground fluorspar to the melt, in the ladle, or adding it to the lade prior to adding the crude iron thereto, in an amount such that the slag is not rendered fluid.
