Titanium - geology.arkansas.gov

In Arkansas, the most important ore minerals are rutile, brookite, and ilmenite. Rutile and brookite each have a specific gravity of over 4.0 and the same chemical formula, but differ in crystalline structure. Both are commonly black in Arkansas and occur as grains and crystals, water-worn pebbles and granules, or crystalline masses.

Ilmenite smelting: the basics - SAIMM

The two main routes to upgrade ilmenite to chlorination feedstock are ilmenite smelting, and the synthetic rutile route. Synthetic rutile is produced by solid-state reactions; for example, in the Becher process (as practised widely in Australia) ilmenite is reduced to a mixture of metallic iron and rutile; the iron is then removed by leaching.

Ilmenite – Tronox

Ilmenite is a naturally occurring mineral comprised primarily of titanium iron oxide, as well as other elements such as magnesium and manganese. It is highly magnetic and can be isolated from other minerals by magnetic separators and other metallurgical separation processes. The TiO 2 content of ilmenite ranges between 45-65 percent.

This invention relates to a process for separating rutile and ilmenite from ilmenite leach tails and is effected by treating the leach tails from an acidic leach to a flotation step whereby gangue is separated from the unreacted ilmenite and rutile. The latter is then roasted at an elevated temperature in a hydrous atmosphere to convert the ilmenite to a magnetic material.

Ilmenite - an overview | ScienceDirect Topics

The most important titanium mineral is ilmenite, as well as Rutile. Most of the commercial ilmenite and rutile deposits are sedimentary heavy mineral concentrates in coastal environments, ocean beaches, or shoreline eolian dunes; only a few are located in an alluvial environment such as riverbeds and deltas (Murphy and Frick, 2006).
