The Pidgeon process is one of the methods of magnesium metal production via a high temperature (800-1400°C) process with silicon as the reducing agent (instead of carbon for iron extraction). The Pidgeon process involves the reaction of magnesium oxide with elemental silicon at high temperatures to form pure magnesium:

The downside of this is expense. You have first to extract (or to buy) the sodium or magnesium. The more reactive the metal is, the more difficult and expensive the extraction becomes. That means that you are having to use a very expensive reducing agent to extract the titanium.

The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas. This is used to make sulphuric acid via the Contact Process. Much like in the Blast Furnace, the calcium carbonate is involved in the production of the slag.
