BF, your right, "few" = "none".
With regard to the chloride technology, there are two aspects to it. One is the obvious IP protection, which to date hasn't been cracked (although Pangang paid $28m to try and buy buy the technology illegally) :

The second limitiation of the chloride route is DuPont / Chemour's unique "Deep Well" waste disposal method. Supposedly this is one of the reasons DuPont's plant in China didn't proceed as the Chinese authorities wouldn't approve a similar waste disposal method.
I also wouldn't assume that it costs more to process a lower grade ilmenite than a higher grade ilmenite. As an example, Chemours get no by-product credits from their process with high grade 60% chloride ilmenite. However, if you take KMR's 50% sulphate ilmenite (with 30 - 33% Fe) and process it into sl@g before converting it to pigment, you also generate a valuable pig iron by-product. A quick check on google suggest the current price of pig iron is $276/tn, which equates to approx $70/tn of ilmenite and would go a long way towards offsetting other costs.
