Electrolytic Processes - an overview | ScienceDirect …

The QIT process (Cardarelli, 2003) is believed to use a calcium fluoride molten electrolyte that floats on a titania-containing slag. On electrolysis, the less electropositive elements are reduced first, collect at the bottom of the vessel, and are then tapped off. The titanium ions are then reduced to produce liquid titanium metal.
