Ilmenite an overview ScienceDirect Topics

Unlike chromite, phase relations do not support crystallization of ilmenite and/or titanomagnetite without simultaneous crystallization of pyroxene and plagioclase. It is therefore not feasible that such concentrations can be achieved by crystal accumulation alone since this would require an extremely efficient sorting mechanism.

WO1990004656A1 Refining of ilmenite by removal of excess

The presence of chromite in significant amount in ilmenite downgrades the market value of the ilmenite. A substantial amount of the chromite may be removed, firstly by a reduction step, secondly by a leaching, aeration or oxidation roasting step and finally by a physical separation step. An optional preoxidation may precede the reduction step and an optional physical separation step may be

Flotation of Chromite — A Review With Applications to

In Australia, ilmenite is produced from beach sand deposits. These deposits contain varying quantities of the valuable minerals zircon, rutile and ilmenite, along with a variety of other minerals. The valuable minerals are upgraded using combinations of gravity, magnetic and electrostatic processing techniques to yield high-grade products. One of the penalty elements present in ilmenite...

Heavy mineral sands ore deposits Wikipedia

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.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
