Ilmenite is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. Ilmenite is the most important ore of titanium [5] and the main source of titanium dioxide, which is used in paints, printing inks, [6] fabrics, plastics, paper, sunscreen, food and cosmetics.
Titanium is a chemical element; it has symbol Ti and atomic number 22. ... [13] when he found black sand by a stream and noticed the sand was attracted by a magnet. [58]

Manganese dioxide: blackish or brown in color, used since prehistoric times (MnO 2). Titanium pigments. Titanium black: Titanium(III) oxide (Ti 2 O 3).
Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [1] It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. [ 2 ]
Heavy minerals (dark) in a quartz beach sand (Chennai, India).Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.
Titanium that was distributed with fake documentation has been found in commercial Boeing and Airbus jets. Now the Federal Aviation Administration, the aircraft manufacturers and supplier Spirit ...
Black sand concentrates often contain additional valuables, other than precious metals: rare earth elements, thorium, titanium, tungsten, zirconium and others are often fractionated during igneous processes into a common mineral-suite that becomes black sands after weathering and erosion.
The first probe was prompted by an incident in which a 737 Max experienced a rare event known as a "Dutch roll," and the second, which also involves Airbus planes, follows a report that ...
