ilmenite in Apollo 11 samples occurs as small tabular grains totally enclosed in pyroxene. Apollo 14 ilmenite contains 0.2-0.6 wt% ZrO 2 and up to 3.9 wt% MgO, which is noteworthy as the whole rock has lower MgO than that from other Apollo sites (approximately 8-8.5 wt%). In addition, ilmenite from one Apollo 14 sample contained

The ilmenite-hematite (FeTiO 3-Fe 2 O 3) solid solution (Ilm ss) commonly occurs in layered intrusions (Harrison et al. 2000).Ilm ss tends to experience subsolidus re-equilibration and phase transformation during different T-f O 2 cooling paths, forming hematite and/or magnetite exsolution and magnetite-rutile intergrowths in ilmenite …
Ilmenite is one of the most significant ores of the metal titanium. It is mined as an important industrial mineral in several deposits throughout the world. Many of those deposits are in heavy placer sands. Ilmenite is very similar in structure to Hematite, and is essentially the same as Hematite with roughly half the iron replaced with ...

Ilmenite commonly shows intergrowth with hematite and magnetite. The crystals are totally opaque and appear as thick tabular crystals or anhedral masses embedded in igneous and metamorphic rocks, or as opaque shapeless sand-size grains. Ilmenite is a weakly magnetic mineral. The color is commonly iron-black, brownish-black, with metallic to sub ...

the main source of supply for the titanium concentrates will be the tin tailings from straits smelter which contain economic ilmenite values. the plant is due to begin operations early in 1976 with an avisage capacity of over 100, 000 tpy ilmenite. a wooddall-duckham twin stream spray roaster process will be used.
Ilmenite ore is leached by sulphuric acid to obtain the main compound of the iron titanium sulfate and oxysulfate. Removing iron sulphate from the solution is followed by hydrolysis reaction to obtain the final product of TiO 2 and H 2 SO 4. Meanwhile, mechanical ball-milling process is one of effective methods for cooperating with acid ...
titanium dioxide and titanium metal. Ilmenite accounts for more than 93% of processed titanium ore, and thus information for titanium ores is presented in the profile to represent the specific mineral ilmenite (Woodruff et al., 2017). Though ilmenite is not used directly in water treatment, iron chlorides produced as a byproduct of

11.4.2 Ilmenite. Ilmenite is a combined oxide naturally occurring in the form FeTiO3, which is also the reduced form in CLC. The oxidized form is Fe2 TiO 5 + TiO 2. It has also been shown that there is a migration of Fe to the surface; thus in practice ilmenite is in part an iron oxide material (Adanez et al., 2010 ).
