PRODUCTION OF TITANIUM SLAG

摘要

A process for producing titanium slag which is low in radioactivity wherein molten titanium slag, produced by smelting ilmenite in the presence of a reductant in a DC electric arc furnace, is separated from molten iron, boron in an amount which is less than 2,5% equivalent B2O3 of the slag is blended with the molten slag which thereafter is allowed to cool to form a glassy phase which contains the bulk of the radioactive elements of the slag before being crushed to particles below about 1mm, whereafter the radioactive elements are leached to leave a titanium slag product which is low in radioactivity.
