However, this nominal recycling rate does not reflect the actual material flow of titanium and its alloys. Because titanium is an expensive metal with a price above US$10/kg, recycling is well established in the smelting process for the primary metal (titanium sponge) and the machining industry for components.

Titanium is the 9th most common elements on the planet. It is found in both oxide and silicate minerals. The earth's crust is 90% silicate with titanium present in. concentrations of between 0 and 1%. In such low concentrations it is not economical to extract. Titanium's oxides meanwhile have concentrations between 15 and >95%.

Other process for producing intermediate grades of titanium dioxide from ilmenite includes the Murso process, which involves high-temperature oxidative roasting (900–950°C), hydrogen gas for reduction, and leaching in 20% hydrochloric acid to remove iron [6]. The Laporte and Benelite processes are very similar to the Murso process [7], [8].
