Ilmenite An ore of titanium Uses and PropertiesHematite The mineral hematite information and pictures

Ilmenite is a black iron titanium oxide with a chemical composition of FeTiO 3 Ilmenite is the primary ore of titanium a metal needed to make a variety of high performance alloys Most of the ilmenite mined worldwide is used to manufacture titanium dioxide TiO 2 Hematite is one of the most common minerals The color of most red and brown rock such as sandstone is caused by small amounts of Hematite It is also be responsible for the red color of many minerals
