DF2014:Ilmenite - Dwarf Fortress Wiki
More Info. Ilmenite is an unremarkable stone that can be found in small quantities within gabbro and orthoclase. Though it is magma-safe, gabbro itself is also magma-safe. In the real world, ilmenite is often mined for production of titanium dioxide, a common white pigment. It can also be used as a source of iron . Ilmenite. [ show][ Select all]

Technology Profile: Titanium Dioxide Production - Chemical Engineering
Ilmenite processing. Initially, ilmenite ores are dried to a moisture content of less than 0.1% and ground to give a mean particle size of less than 40 mm. This prevents heating and premature reactions downstream. The finely ground, titanium-bearing ore is dissolved in sulfuric acid and water, forming a solution rich in metal sulfates.
