Dear James,
I don't have specific knowledge of this,
but such a question is best aimed at the mailbase list
arch-metals which specifically deals with ancient and
historic metallurgy.
I know that Effie Photo-Jones,now at Scottish Analytical
Services for Art and Archaeology, Glascow, carried out
work on the bloomery smelting of Ti-rich iron ores from
Greece, but conditions are rather different from that for
a blast furnace.
