The market outlook graphs don't show prices improving - just their expectations. The graphs show the zircon price fall has slowed and rutile / synthetics rutile prices have stabilised.
They say the market for premium mineral sands products is stable compared to other mineral commodities (?iron ore, ?copper). I presume that means it is stable compared to non-premium mineral sands products (?sulphate ilmenite, etc).
A bit like an astrology reading. That premium product prices have stabilised is about all that is clear.
I suspect that the price of premium product is rising and the differential between premium and lower quality products is widening - the latter may still be falling.
