Ann: 3Q 2016 Operations Review-MDL.AX, page-4

I ripped this bit out of the psiot by HC Trader on the MZI thread.
Iluka Resources (ASX: ILU) is one of the largest players in the global mineral sands industry, but even its rutile production profile is in freefall. In 2014 the group produced 177,000 tonnes of rutile.
Paul Young from Deutsche Bank crunched the numbers in July, forecasting production to fall to 132,000 tonnes in the 12 months to December 31, 2016.
By 2019, the analyst expected production to plummet to 29,000 tonnes – that was prior to Iluka’s takeover bid for Sierra Rutile, which while still to be completed, will significantly boost Iluka’s rutile resources and production.

Basically it means there is likely to be a decent tightening in the prices achieved for TiO2 slag.

But one needs to take this with a grain of salt because Iluka can re- start one or more of their Synthetic Rutile Kilns.
