Chromite is an iron chromium oxide: FeCr₂O₄. It is an oxide mineral belonging to the spinel group. Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr₂O₄); substitution of aluminium occurs leading to hercynite (FeAl₂O₄).

Chromite is found in peridotite from the Earth's mantle. It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum. The vast Bushveld igneous complex of South Africa is a large layered mafic to ultramafic igneous body with some layers consisting of 90% chromite making the rare rock type, chromitite. The Stillwater igneous complex in Montana also contains significant chromite.

The only ores of chromium are the minerals chromite and magnesiochromite. Most of the time, economic geology names chromite the whole chromite-magnesiochromite series: FeCr₂O₄, (Fe,Mg)Cr₂O₄, (Mg,Fe)Cr₂O₄ and MgCr₂O₄. The two main products of chromite refining are ferrochromium and metallic chromium, for those products the ore smelter process differs considerably. For the production of ferrochromium the chromite ore (FeCr₂O₄) is reduced with either aluminium or silicon in a aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting and leaching process.

Liam John Neeson,OBE (born 7 June 1952) is an Irish actor who has been nominated for an Oscar, a BAFTA and three Golden Globe Awards. He has starred in a number of notable roles including Oskar Schindler in Schindler's List, Michael Collins in Michael Collins, Peyton Westlake in Darkman, Bryan Mills in Taken, Qui-Gon Jinn in Star Wars (the film Star Wars Episode I: The Phantom Menace and episodes of Star Wars: The Clone Wars), Alfred Kinsey in Kinsey, Ra's al Ghul in Batman Begins, and the voice of Aslan in The Chronicles of Narnia film series.

He starred in other notable films such as Excalibur, The Dead Pool, Nell, Rob Roy, Les Misérables, The Haunting, Love Actually, Kingdom of Heaven, Taken, Clash of the Titans, The A-Team, Unknown and The Grey, as well as smaller arthouse films (e.g. Deception, Breakfast on Pluto, Chloe). He was ranked at number 69 on Empire magazine's 100 greatest movie stars of all time in 1997.

He was born in Ballymena, County Antrim and educated at St Patrick's College (now St Patrick's, Dundonald), Ballymena Technical College and Queen's University Belfast. He moved to Dublin after university to further his acting career, joining the renowned Abbey Theatre. In the early 1990s, he moved again to the United States, where the wide acclaim for his performance in Schindler's List led to more high-profile work. He is widowed and lives in New York with his two sons.
