Selection of titania enrichment phase in the blast furnace slag bearing titania
In the blast furnace slag, titanium disseminates in various mineral phases(perovskite, spinel, Ti-rich diopside, Ti(C、 N) and titannaugite). Based on the technique of selective precipitation, titanium was studied. The first step of this technique is to select the titanium enrichment phase on which the most titania can be concentrated by optimizing the heat treatment and appropriate additives. The result was made by calculation and analysis that Perovskite in the slag is the best enrichment phase. The conclusion was validated by experiments.
